OK, I can see its done on point. Once you figure out what size the 4 block is - add your white strip on 2 opposing ends. Then cut more white strips and do a block, strip, block, strip, etc. The only part I really can't help with is the side white end triangles as we don't know the size of the blocks. Lay your blocks with white in diagnol row to the size you want the quilt to be then that will dictate how many block, strip, block, strips, etc. you need to connect. Good Luck!!
