That is a 9 patch set in a hole in the barn door, a very traditional pattern. If your 9 patch square pieces are cut at 2.5", the light blue strips should be 3", the white at 2.75". Those are what I think the proportions are, not necessarily the sizes of the original.
BTW, I often download pix to give me ideas for later. Quilters 'borrow' a lot.
I, also have to keep even the weight of the sheet off my bum foot/ankle. DH and I first went to separate quilts, then separate bedrooms. You are far from alone on this. We have had to make a point of cuddling at other times than sleep times.
