When I make these, I add a 4-1/2 (finished)border (cut 5" wide) then a final border of the blocks. Use something that reads 'solid', just to calm it down. I make these for my kids' friends for graduation. For the guys, it's fabrics of deer, moose, elk - they are all hunters. Because the fabric isn't cohesive in colors, I use that solid border to tie everything together. If this doesn't make sense, I'll try to post a picture tonight.
As for "Yellow Brick Road", it's just a name.
