I like chevrons, but I do find the fabric tricky to work with in quilting. I have had some success using a tone on tone chevron as a small border or a binding. In blocks, it can be not all together pleasing unless you give very careful attention to your cutting. I have been toying with the idea of trying a stack and whack type block, just to see what I could come up with-- it would be fairly subtle as far as kaleidoscope blocks usually go, but it might be fun.
