Make the most of your  

Hello & Happy Sunday, Judy. THANK YOU❤

I have an old one, actually I have 2 older ones (one was my mothers) that are different sizes. I mark the slots with ruler tape now since I've made the exact same mistake of misjudging the correct slot. They do help to get accurate pieces. Thank you for your video!

Love my stripology ruler, but I use the stickers t9 mark cutting spots

What size is that stripology ruler?
