So the numbers are killing you, eh?
Well,not to worry - - tell me what you need to know, and maybe we can figure it out together ...
do you need to know how many blocks to make to create a certain size?
Are you thinking you might want to add some sashing or something?
I love numbers, and a number of us don't mind messing around with them ...
if you don't know which size block you want to create, spend a bit of scrap time and make one of each size! sometimes, the size of of the pieces makes the decision about which size block you will want to make.
And, HAVE FUN! <g> <wave>
