Hooray!! Glad you are making such good progress.:thumbup:
In the sampler, there is a sashing between the two blocks. Are you going to use it? If so, it should be the same length as the side measurement of both blocks. The sashing also makes it less obvious the blocks are based on different basic patterns - i.e. one is based on a 4 x 4 grid, the next based on a 5 x 5 grid. The sashing will make your individual blocks 'shine', being set off, unique. :thumbup:
