I purchased some of mine at my LQS, others I purchased at different quilt conventions/shows. Each time I go I see more that would look great "canned". I better get going on making my jar quilt soon or I might end up with enough fabrics to make 10 jar quilts!!!!
Numa just posted a "bountiful blessings" quilt of jars, crates and baskets of fruits and veggies. It really is awesome.
