I ❤ crazy quilting, beading & ribbon embroidery . . . A word of caution would be to start with solid colors or use prints with a very tiny pattern. This ensures that your fancy stitching will show up. If making a block of every color and working with thread of every color is too much for you on your first color adventure, try using threads of every color on black blocks. Here is a RR block stitched several years back by Jo Newsham of NZ using lots of intense color on a black background.
