The fabrics will ALL work well together. What concerns me is the stripes. I'm anal enough that I would have to have all the stripes going in the same direction. If that doesn't bother you - jump right in to the block design you have picked out Alternatively, use the stripes for sashing or for borders and make the block with your other fabrics. I would LOVE to see that diagonal stripe as a binding - saves the effort of cutting it on the bias. Please thank your family members for their service - may God bless them and all your family.
