🧶 Pattern Instructions

💡 Tip: Count your stitches at the end of each row to ensure you maintain 14 stitches throughout.
  1. Row 1
    With main color, ch 15. Sc in 2nd ch from hook and in each ch across. (14 sts)
  2. Rows 2–17
    Ch 1, turn. Sc in each st across. (14 sts) — work 16 rows total to reach approximately 4 inches (10 cm) in height. This forms the case front.
Row counter:
💡 Tip: Weave in ends from the foundation chain before seaming.
  1. Rows 1–17
    With main color, ch 15. Sc in 2nd ch from hook and in each ch across (14 sts). Ch 1, turn. Sc in each st across for 16 more rows. (14 sts) — This piece matches the front exactly.
Row counter:
💡 Tip: The chain loop should be large enough to slip a 0.75-inch (2 cm) button through comfortably. Test-fit before fastening off.
  1. Row 1
    With main color, ch 15. Sc in 2nd ch from hook and in each ch across. (14 sts)
  2. Rows 2–7
    Ch 1, turn. Sc in each st across. (14 sts) — work 6 additional rows (Rows 2, 3, 4, 5, 6, 7), creating a flap approximately 2.5 inches (6 cm) tall.
  3. Row 8 (button loop row)
    Ch 1, turn. Sc in first 4 sts (4 sts), ch 6 (this chain forms the loop), skip next 6 sts, sc in last 4 sts (4 sts). (14 sts total: 4 + 6-chain loop + 4)
  4. Row 9
    Ch 1, turn. Sc in first 4 sts, sc in each of the 6 chain sts, sc in last 4 sts. (14 sts)
Row counter:
💡 Tip: Use a yarn needle and matching thread for neat, invisible seams. Go slowly to avoid puckering.
  1. Step 1: Attach flap to back
    Hold the back piece and flap with wrong sides together, aligning one long edge of the flap with the top edge of the back piece. Using yarn needle and main color, whip stitch along this edge, working through both layers. Fasten off. (Flap now hinges from back piece) Note: Wrong sides together means the right (public-facing) sides will be visible on the outside of the finished case.
  2. Step 2: Seam case sides
    Place front and back pieces with wrong sides together, aligning all edges. Seam down both long sides (left and right) using whip stitch, working through edge stitches only. Leave the top edge open (case opening). Fasten off and weave in ends. (14 sts remain open at top) This maintains the same orientation as Step 1, with right sides facing outward for a neat, finished appearance.
  3. Step 3: Seam bottom edge
    Close the bottom edge with whip stitch, working through the bound-off stitches of both front and back. Secure and weave in ends. (Case is now fully seamed except at the top opening)
Row counter:
💡 Tip: Work the trim stitches loosely so they lie flat and don't pucker the case body.
  1. Round 1
    Attach contrasting color yarn at a bottom corner with st">sl st. Ch 1. Sc evenly around the entire case, working through the outermost loop of each edge st and into corners. To calculate stitch count: measure the perimeter (approximately 20 inches for this case) and multiply by your gauge of 4 stitches per inch, yielding approximately 80 stitches; however, the case opening and fabric properties may reduce this. Aim for 50–56 sts around based on even spacing. Sl st to first sc to join. (approximately 50–56 sts)
  2. Round 2
    Ch 1. Sc in each st around. Sl st to first sc to join. (approximately 50–56 sts) — This second round creates a smooth, finished edge.
  3. Fasten off
    Cut yarn, pull through last loop, and weave in end.
Row counter:
💡 Tip: Test the button closure several times to ensure the loop is the right size and the button holds the flap shut securely.
  1. Step 1: Position button
    Close the flap over the front of the case. Note where the button loop aligns with the front piece. The button should sit centered on the case front, approximately 1.5 inches (4 cm) down from the top edge.
  2. Step 2: Sew button
    Thread a needle with main color yarn (or matching thread). Sew the button securely to the front piece with 4–6 passes through the button holes, creating a strong attachment. Knot and weave in the thread on the inside of the case.
Row counter:

✂️ Finishing

Weave in all remaining ends using a yarn needle, tucking them between the front and back layers where possible. Block the case gently by laying it flat and lightly dampening with water; allow to air dry completely. This helps even out the edges and ensures a neat appearance. The flap should fold neatly over the front and the button closure should align smoothly without bunching. Once dry, the case is ready to use.

Questions About This Pattern

Absolutely — just match the weight (Worsted). You'll need about approximately 130 yards, so make sure your substitute has enough meterage. Acrylic is budget-friendly and machine-washable; wool gives better stitch definition and drape.
Yes! This is one of the friendlier patterns to start with. You only need to know: sc, ch, sl st, st(s). Work slowly, count your stitches at the end of each row, and don't be afraid to frog (rip back) and redo a section — that's how everyone learns. Budget about 3-5 hours; beginners often take a bit longer, and that's totally fine.
Usually it's the joining or finishing — where individual sections meet and need to align. Read through the entire pattern once before you start so there are no surprises. Use stitch markers generously to track your place, especially in rounds. If a section looks wrong, count your stitches before proceeding — catching an error early saves a lot of frogging later.
For this pattern, gauge is "16 sc x 16 rows = 4 inches (10 cm) in single crochet". For decorative or non-fitted items it's less critical, but matching gauge ensures you use the right amount of yarn and get the proportions the pattern intends. If your swatch is too small (too many stitches/inch), go up a hook size. Too large — go down.
Hand wash in cool water with mild soap. Do not bleach. Lay flat to dry or tumble dry on low. Acrylic yarn is durable and resistant to fading. Avoid prolonged exposure to direct heat or sunlight. If the button becomes loose, simply resew using the existing holes. A general rule: when unsure about the yarn, hand wash in cool water with a drop of gentle detergent, squeeze (don't wring), and block flat to dry. This is safe for almost every fiber.
Each section builds on the last, so yes — follow them in order. That said, some finishing sections (like embellishments or optional edging) can be skipped if you prefer a simpler look. Read through all sections before starting so you understand how the pieces fit together and can plan your yarn usage across sections.
