Make A Fabric Chalkboard

Supplies:
To make a chalkboard with a finished size of14x10.5inches, you will need
chalk cloth cut to 12x10.5"
a heavier fabric cut in these sizes:14.5x10.5" (backing), 4x4.5" (pocket), and 4x10.5" (side piece)
coordinating bias tape
sewing machine with a zig zag stitch
optional: ribbon or elastic to hold it closed
Step 1:
Hem under one of the short edges of the pocket.

Step 2:
With right sides together, layer the pocket on the edge of the chalkcloth with raw edges together. Layer the side piece on top (wth the right side facing the chalk cloth. Sew together with a 1/2 inch seam.
Step 3:
Flip the side piece and pocket to the front and topstitch down. Reinforce the leading edge of the pocket.
Step 4:
Layer the chalkcloth on top of the backing. Match up the pocket and side piece to the short edge of the backing with right sides together. Sew together with a 1/2 inch seam.
Step 5:
Flip so the the chalkboard is back to back and topstitch the edge. Reinforce the leading edge of the pocket.
Step 6:
Cut the end of the bias tape in a triangle and fold over. Sew along the chalkcloth and backing, catching both layers with a wide zig zag stitch. Go slow and make sure the edge of the zig zag almost touches the open edge of the bias tape.
Step 7:
Finish the bias tape by cutting another triangle and folding the end over.
The Finished Product!
(I didn't have any chalk, so I am modeling crayons here)
Voila!
Roll it up with a ribbon or sew a loop of elastic to keep it rolled up. Make a T&T sherpa or terry cloth wipe to go with it.
