I made these for a friend out of the kids baby clothes and they turned out great despite all the different textures of fabrics. Needless to say all of the knits, T-shirts etc...had to be stabilized and then cut to specific size and then I had to find a pattern that would work with the various colors. This was a project that took a long time so if anyone decides to do a project like this, be prepared to invest a lot of time in it.
Happy Quilting!!
