Here is an easy little coin purse.
I made two, one for safety pins and one for all my buttons. I put a small safety pin through the top flap and sewed a button onto the flap of the other as labels so I’d know which purse was for which.
Cast on 21 sts, st st for 50 rows, end K row.
Row 1: K4 P13 K4 (creates garter stitch border to prevent rolling)
Row 2: K
Repeat these 2 rows 5 more times
Decrease flap, Row 1: K4 P to last 4 sts, K4
Row 2: K4, K2 tog, K to last 6 sts, K2 tog, K4
Repeat these 2 rows until 9 sts remain.
Row 1: K4, cast off 3, K2
Row 2: K3, yo, K3
From here to end K each row, decreasing 1 st at beg and end of each row until 3 sts remain. K 1 row. Cast off, sew up sides and add button.
