This first quality sample is an odd size (78 L x 72 w) but could work with a twin comforter insert. It has ties inside the corners to secure your insert.
If you sew, it would also be any amazing opportunity to have a large swath of high quality, hand block printed fabric for your own projects. 100% cotton. Pre-washed and dried.
Please measure your bed and insert before purchase to ensure that you will be happy with the size. All sales final.
