We all have leftover numbers and alphas right???
So I dug some out and found matching background paper, in this case it was a 6X6 pad.
Not only mix up the numbers but spell out numbers using the alphas. Six uses up those x that we are stuck with. I even used commas as counters as you can see.
My next step was to use these on a layout.
I still have some left over but they can be put on cards etc.
