Abbreviation	Stitch
ch	chain
sc	single crochet
sl st	slip stitch
st(s)	stitch(es)
BLO	back loop only
YO	yarn over

Special Notes

• The number of sc on your D-ring will depend on both ring size and yarn. Adjust as needed.
• For a neater look, use cotton yarn.
• Work sc in the back loop only (BLO) for the ‘fold’ row to create a crisp bend at the base of the strap.
• Adjust strap length as desired; sample makes a 13″ strap (approx. for wristlet).

Instructions

1. Attach Yarn to D-Ring

• Make a slip knot.
• Hold the D-ring with its flat side facing up.
• Insert hook into the ring, YO, pull up a loop. YO, pull through both loops on hook to form a sc on the ring.
  Save
• Repeat sc stitches evenly across the flat of the D-ring until you have covered it.
  • Sample: 8 sc on a 4cm D-ring.
  • The exact number will depend on your ring/yarn—cover the flat edge snugly and evenly.

2. Strap Row Section

Rows 1–6 (or until piece measures about 1 inch):

• Ch 1, turn.
• Sc in each st across (through both loops).
• Repeat for a total of 6 rows (or until you reach approx. 1 inch in height).
  Save

3. Fold Row (Creates Crisp Bend)

• Ch 1, turn.
• Sc in each st across but through the back loop only (BLO).
• This row creates a defined fold for your strap.

4. Main Strap – Regular Rows

• Ch 1, turn.
• Sc in each st across (through both loops).
• Repeat this row until the entire strap including the first 1″ section and bend measures about 13 inches (sample used a total of 79 rows after BLO row).
• Adjust total length to fit your wrist or desired usage.
  Save

5. Assembly – Seaming Ends

• Fasten off, leaving a long tail (about 12″/30cm) for sewing.
• Fold the strap to bring the starting D-ring edge and the live working edge together, aligning both ends.
• With a yarn needle, sew through the front loops of both edges (from both the starting and final row), whip-stitching securely to join the strap into a loop.
• Weave the tail(s) in securely and knot as needed.
  • If you only have one end/tail, make a knot as follows: insert needle under a nearby loop to form a small loop, then pass yarn tail through and pull snug. Weave in end to secure.
    Save

6. Finishing Edges (Optional)

For a clean and professional finish:

• Join yarn at the side edge.
• Sc evenly around all edges of the keychain (insert hook into natural row end “holes”), working sc into each spot around the entire loop.
• When you reach the beginning, fasten off and use your yarn needle to hide the end—pull it under edge stitches and knot subtly near sewing seam as needed.
• Repeat for the opposite edge if desired.
  Save

Pattern Correction

• The original instruction to “sc in BLO” is meant only for the designated bend/fold row. All other rows are worked through both loops unless otherwise noted.
• The number of sc on the D-ring and strap lengths are easily adjustable.
• The sample uses 8 sc on D-ring, 6 rows for initial 1″, followed by 1 BLO row, then 79 rows for total strap, but measure against your own wrist/desired length.

Tips

• Test fit length before sewing ends by wrapping around your wrist.
• If ends are uneven after sewing, edge rounds of sc will help smooth them.
• For a chunkier strap, use a thicker yarn or add more sc to both D-ring and rows.
• To match store-bought straps, use bright solid or variegated cotton for impact.

Conclusion

With minimal supplies and basic crochet skills, you can quickly create a sturdy and stylish keychain strap. This project is ideal for customization and makes practical, beautiful gifts. The option to clean up edges with a sc border gives a highly finished look, comparable to high-end store brands.
