Evergreen Triangle Cup Cover Free Pattern: A Mountain Cabin Crochet Cup Sleeve

Evergreen Triangle Cup Cover: A Mountain Cabin Crochet Cup Sleeve

If you have never held a crochet hook before, this is the perfect first project to make you fall in love with the craft. This Evergreen Triangle Cup Cover is a small, flat triangle of pine-green single crochet with a little brown "trunk" band at the bottom, folded and seamed into a cozy cone that hugs a tapered takeaway cup. It works up in about an hour, uses only a few yards of yarn, and gives you a finished, useful, gift-worthy object on your very first try. The back-loop-only stitching creates gentle horizontal ridges that look like evergreen needles and tree bark, and the matte woolen texture feels warm and rustic in your hand. Slip it over your morning coffee or tea and you have a little piece of mountain cabin magic to carry with you all day.

Materials Needed

• Yarn: Worsted weight (category 4) acrylic or wool blend, approximately 40–50 yards total — about 35–45 yards of pine green and 5–8 yards of dark brown.
• Crochet hook: H/8 (5.0 mm).
• Stitch markers: 2–3 removable markers (or a scrap of contrasting yarn) to mark your first stitch and your decrease points.
• Tapestry needle: A blunt-tipped yarn needle with an eye large enough for worsted yarn, for seaming and weaving in ends.
• Scissors: Any sharp pair for cutting yarn.
• Measuring tape or ruler: For checking your gauge swatch.
• Finished size: Approximately 4.5 inches (11.5 cm) tall and 3.5 inches (9 cm) across the top opening when folded and seamed, fitting a standard 12–16 oz tapered takeaway cup.

Abbreviations and Beginner Glossary

Every abbreviation used in this pattern is listed below. Read through them once before you begin — no prior knowledge is assumed.

• ch – chain. Make a slip knot on your hook, wrap the yarn over the hook, and pull it through the loop on your hook. That is one chain. A row of chains is your starting "foundation."
• sc – single crochet. Insert your hook into the stitch, wrap the yarn over the hook, pull up a loop (you now have 2 loops on the hook), wrap the yarn over again, and pull it through both loops. One single crochet made.
• st / sts – stitch / stitches. One completed stitch, or several of them.
• sc2tog – single crochet two stitches together (a decrease). Insert your hook into the first stitch, pull up a loop, insert your hook into the next stitch, pull up a loop (3 loops on hook), wrap the yarn over, and pull through all 3 loops. Two stitches become one.
• BLO – back loop only. Every single crochet stitch has two top loops: a front loop (closer to you) and a back loop (farther away). Working in the back loop only means you insert your hook under just the back loop, leaving the front loop free. This creates the ridged texture.
• sl st – slip stitch. Insert your hook into the stitch, wrap the yarn over, and pull it through both the stitch and the loop on your hook in one motion. It makes a nearly invisible join.
• turn – flip your work over so you can work back across the row you just made.
• RS / WS – right side / wrong side. The right side is the "public" face of your work; the wrong side is the back.
• fasten off – cut the yarn a few inches from your work, then pull the tail all the way through the last loop on your hook to lock it.
• join – attach a new color or new yarn by making a slip knot on your hook and slip stitching into the place where you want to begin.
• whipstitch – a simple seaming stitch: bring the needle up through both layers, over the edge, and back down, repeating in small even stitches.
• mattress stitch – a seaming stitch that goes side to side between the edge stitches of two pieces, pulling them together invisibly.
• weave in ends – thread a yarn tail onto a tapestry needle and run it back and forth through the fabric so it disappears and cannot unravel.

Gauge

Gauge: 16 sc x 18 rows = 4 inches (10 cm) in single crochet, unblocked.

Gauge simply means how big your stitches are. If your stitches are bigger than the pattern expects, your cup cover will come out too loose and slide off the cup; if they are smaller, it may not fit over the cup at all. To check, crochet a small square about 5 inches wide: chain 21, then single crochet in each chain and in each stitch for about 20 rows. Lay a ruler across the middle of the square and count how many stitches fit in 4 inches, then count how many rows fit in 4 inches. If you have more stitches than 16, your tension is tight — try a larger hook. If you have fewer, your tension is loose — try a smaller hook. Always measure in the middle of the swatch, never at the edges, because edge stitches stretch.

Beginner Tips Before You Start

• Count every row. This pattern shrinks by one stitch per row, so a miscount early on will throw off the whole triangle. Say the count out loud as you work.
• Use a stitch marker. Place a removable marker in the very first stitch of each row so you always know where the row begins and ends. Move it up as you go.
• Do not pull the yarn too tight. New crocheters tend to choke the yarn. Keep your loops relaxed and let the hook do the work — tight stitches make a stiff, undersized cover.
• Remember the ch 1 does not count as a stitch. The turning chain at the start of each row is just a "ladder" to get your yarn up to the next row. Never work into it or count it.
• Work in the back loop only (BLO) every row. Look at the top of each stitch: two loops. Push your hook under the far loop only. This is what gives the cover its bark-and-needle ridges.
• Keep your brown yarn nearby. You will switch colors at the very end, so set the brown ball beside you now and don't bury it in your bag.

Step-by-Step Instructions

Notes: The cover is worked flat as a triangle in decreasing rows, then folded in half and seamed along one short edge to create a cone. Ch 1 at the beginning of a row does not count as a stitch. Work in the back loop only (BLO) of each stitch throughout. Change to brown for the final section to form the trunk base.

Triangle Panel (worked flat, pine green)

Row 1: With pine green, ch 36. Sc in the 2nd ch from hook and in each ch across. (35 sc)

Row 2: Ch 1, turn. Sc in first st, sc in each st across to last 2 sts, sc2tog over last 2 sts. (34 sc)

Row 3: Ch 1, turn. Sc2tog over first 2 sts, sc in each st across. (33 sc)

Rows 4–33: Repeat Rows 2–3, alternating the decrease between the end of the row (Row 2 style) and the beginning of the row (Row 3 style), until 3 sts remain. (3 sc) — that is 15 repeats of the two-row sequence, ending on a Row 3-style row.

Row 34: Ch 1, turn. Sc2tog over first 2 sts, sc in last st. (2 sc)

Row 35: Ch 1, turn. Sc2tog over both sts. (1 sc) Fasten off pine green.

Trunk Base (worked flat, brown)

With the right side facing, join brown with a sl st in the bottom right corner of Row 1 (the wide foundation edge).

Row 1: Ch 1, sc evenly across the bottom edge, working 1 sc in each foundation ch. (35 sc)

Row 2: Ch 1, turn. Sc in each st across. (35 sc)

Row 3: Ch 1, turn. Sc in each st across. (35 sc)

Fasten off brown, leaving a 12-inch tail for seaming.

Assembly and Finishing

1. Fold: Fold the triangle in half with right sides together, aligning the two short side edges that run from the wide base up to the pointed tip. The brown band should sit at the bottom, and the point at the top.
2. Seam: Thread the 12-inch brown tail onto your tapestry needle. Using whipstitch or mattress stitch, sew the two aligned side edges together from the base all the way up to the tip, creating a conical sleeve. Work small, even stitches and keep your tension gentle so the seam does not pucker. Do not seam the bottom edge or the top opening — those stay open.
3. Weave in ends: Thread each remaining yarn tail onto the tapestry needle and run it back and forth through the inside of the fabric for about an inch, then snip it close. Never tie a knot; weaving hides the tail and locks it in place.
4. Turn: Turn the cover right side out. The brown trunk band sits at the bottom, and the pine green triangle forms the tapered body.
5. Block (optional but recommended): Lightly mist the cover with water, shape it over a tapered cup or a glass, and let it dry completely. This relaxes the stitches and evens out the ridges. Do not iron acrylic yarn — the heat will melt it.
6. Wear it: Slip the cover over a tapered cup, with the pointed tip at the top and the brown band at the base.

Pro Tips and Variations

• Change the colors: Swap the pine green for snowy white and the brown for charcoal gray for a winter birch-tree look, or use a variegated green to mimic dappled forest light.
• Adjust the size: For a wider cup, start with a longer foundation chain (add 2 chains for every extra stitch of width) and work the same two-row decrease sequence until 3 stitches remain. For a shorter cup, stop decreasing earlier and fasten off at 5 or 7 stitches.
• Substitute yarn: Cotton yarn gives a crisper, washable cover that holds its shape well; a fluffy wool blend gives a softer, fuzzier "snow-dusted" texture. Just check your gauge again, since different fibers behave differently.
• Add a little sparkle: Work the final brown row with a strand of metallic thread held together with the brown yarn for a subtle frosty glint on the trunk band.
