I'm unable to finish projects unless I finish them as I go. This time, I sew single tiles, ready with a backing, so in the end I will just connect the tiles. The reptile quilt is still waiting for its backing because during the past months, I just did not have the strength to bast a sandwich. In this case, there is not much left to do, once I have enough tiles for a quilt size. It doesn't have a batting, just 3 layers of fabric at least. The sewing method makes it rather heavy -- and hopefully sturdy enough for passing a test by a determined toddler.
Or what about a mix of top and reverse tiles?
This way, I would get a double-sided quilt.
