Welcome to the Quilting Board!
Sewcrazygram asked what I was thinkin about the altos which brings to mind when the ex and I parted ways I sort of hid his L shaped ruler in my things because I used it in sewing. I am thinking that somany things that were made for men us ladies can use and make our quilting so much easier. WTG Tall on finishing the blocks you did. We look forward to many more and all the pics that gowith thm. WTG Miss Penny!!!
I bought one of those the first year I started quilting and only ever used it as a cutting board (a really expensive cutting board). It was a shame not to get all the intended use out of it, so sold it at a quilt shop yard sale -- maybe you got it?
