I went through my 2.5 inch green scraps and found enough long pieces (at least 22 inches) to make 15 Kaleidoscope blocks. These will finish at 8 inches.
Last year I made 12 inch Kaleidoscope blocks and the first few (and a couple since then)
Last year I made 12 inch Kaleidoscope blocks and the first few (and a few since then) had the "volcano effect"...middle of the block did not lay flat.
One of the tips I have found to eliminate the "volcano effect" is to be sure the tip of the ruler and the side of the ruler are lined up properly before cutting. If the outside of the block is not lined up exactly with the ruler (as seen here) that's usually okay (for my blocks). Every once in a while my seam allowance is a little off and I end up with a some buckling in the middle of the blocks and those I starch into submission.
In case you haven't guessed...green is the color of the month for the Rainbow Scrap Challenge.
