This was one of the first quilts I ever made, and I don't remember the name of the pattern. It's an octagon Kaleidoscope-type. Somehow the pattern also produced a number of small 4-piece (square) kaleidoscopes that you can see between the lattice strips. Also, there's a purple corner in each of the larger kaleidoscope blocks. (How did that get there?) Can anyone help me find the pattern?
