I did two like this. Measure each decal/design, deduct 1 inch vertical and horizontal (for seam allowance) and mark on graph paper where you want in (using each square as one inch). I allowed a 2 inch spacing (minimum) between each design piece. When the whole thing is on the graph paper, you're ready to cut fabric but don't forget to add seam allowance to each fabric piece. there will be lots of Y seams as you go along.
