I went to the closest fabric store yesterday to get a tumbler ruler - the person who waited on me had never heard of one. But I had to walk by two totes of some of my favorite fabrics - Jason Yenter in the Beginning, Jenny Beyer and the Northcutt Artisan line for $3.99 a yard. I had deliberately left my debit card in the car - it's a good thing. The store is closed until Monday so the staff can go to Padukah. Hopefully, by then I will have forgotten about the sale.
I came home and made a tumbler template. Now to collect fabrics from my generous stash to try it out.
