Wash bag according to the yarn's instructions and block flat, making sure that the marked stitches are precisely the first and last stitches on either side.

When blocked and dry pin the bag flat, matching the front pattern to the back.

Crocheted Strap

Start at the bottom corner of bag and slip stitch bottom closed.

Row 1

Ch 1, and passing the hook behind both the first stitch of the front and the last stitch of the back, sl st in every other row along the side of the bag.

At the top corner of the bag, ch for 36 inches (91.44 cm).

Weave in ends.

Fringe bottom of bag with 2 strands of MC placed about 2 sts apart.

Trim to around 1 inch (2.54 cm) long.

Making & attaching the lining

Use a fabric of your choice for the lining.

Try to match your fabric's care instructions as closely as possible to your yarn care's instructions.

Pre-wash the fabric according to its care instructions.

If the fabric is thin or slinky, cut some interfacing in the same shape and hold it together with the fabric while performing the following steps.

Interfacing should be on the "wrong" side of the fabric and sandwiched between the lining and the knit bag.

Measure the finished bag width-wise between the crocheted edges.

Mark your fabric as that wide, plus ½ an inch (1.27 cm).

Measure your bag from just inside the top edge of the bag, to just above the top of the fringe.

Mark your fabric as twice that long plus 2 inches (5.08 cm) for a hem.

Fold the fabric so that the bottom of the bag lining is the fold line.

Fold both top edges down 1 inch (2.54 cm) to the outside.

Pin in place.

Sew the side seams first, 1/4 of an inch (0.64 cm) in.

Working around the circumference of the lining, sew the hem in place.

With wrong side still out, pin lining inside bag.

Line up the lining's side seams with the very side seams of the bag.

Using a nearly invisible stitch, hand-stitch the top fold of the lining to the inside top of the bag.

For consistency, sew along the same round of the bag and try to make a stitch for each "purl bump" in that round.
