Hi Susan,
Point your browser to eBay and search for John Flynn. Scroll through the list and you will find the Wheel of Mystery quilt kit(s). I have four of the pastels... that means 80 blocks to make. However, with them already cut, all I have to do is sit down and sew. There is no right or wrong as to how they go together color-wise except light to dark, dark to light or medium, etc.
Also, with sewing machine feet there are dozens that fit all machines. I would google your sewing machine manufacturer; i.e., Brother, Janome, etc., and go to their home pages. They usually have a good listing of what each machine can do, what feet that are available, the uses of said feet, etc.
I dearly love the walking foot for quilting straight lines!
Back to work for me...
Anita
