This is a corner to corner pattern so the triangles are made from rows of blocks. Each triangle can be extended to chosen size so can be made bigger or smaller. I have chosen to slightly mismatch the stripes but they could be aligned to be symmetrical. I used the following colours: cerise, yellow, mint, blue (saxe, turquoise, sky), black, white, grey, lavender

An ideal scrap project or one that could have custom colours.
