Sew your potholder by folding the twine the length you want.

Use a wide zigzag stitch to attach the two pieces together.

When you get to the end, keep the needle in place.

Turn the piece and continue to add more twine from the spool.

Sew it to the previous piece. 

Continue adding lengths until you get to the size you want.

Finish with back stitches and then cut the twine off from the spool.
