which one of these are you going to make?
You have three different patterns although Kaleidscope and Stack N Whack are basially the same.
Althugh The Stack N Whack an be several patterns.
Having said that, all look best in bold patterns and color.
Small designs don't work but needs large and bold with patches of color. If you want to try it take one of the hinged mirrors and check the design.
And when selecting fabric, be sure and get what the pattern or design calls for in the number of repeats.
Repeat designs should only be considered down the selvedge edge. Although there is a strip of repeats down the center, they don't always match up with those along the edge. The center ones can be used for another set of blocks depending on the pattern.
