Yes, that was how I made my first one...45 degree triangles and hst corners. Mine was scrappier in that it didn't form orange peels.....and I alternated blocks....lite corner triangle block , then dark.......it was an idea I saw in a mag....did not take a pic of, nor do I have it.....that's how I plan on doing this only in batiks...it will truly look like a kaleidoscope....I have a small collection of them.....they are fascinating to look thru! Ah, let's see, where's that TO DO LIST!
