I used strips cut 3/4" , fastened them with 1/2" screws to my "Back" board. I held each tool on the board after placing the first/last screw, pulled the strap over the tool so it was held firm but not too tight to remove easily, marked strap for a screw, punched a hole in the leather and placed the screw. Works great. One thing I learned right away, don't place most used tools too high to reach when siting at the bench. Least used doesn't matter much. Also, longer tools like leather shears need to have more space between the rows of tools. I didn't tool any design on my straps but that does look nice. Length for straps just happened to be what I had available to cut them from. Don't get the most used too far left or right side of center of your stamping/work area as well.
