Gudrun's ruler rocks. It is well-crafted easy-to-use Swift accurate just a real time-saver in your sewing room makes cutting so much less of chore and always perfect results thank you for demonstrating the use of 1/4 inch mark. I take care in folding fabric to ensure no elbows. The stripology rer has great top a d bottom markings to ensure both folds are parallel. I think if you experiment more with putting fabric in ideal situ with folds you will become a convert.
Great tip! I will try this next time I cut binding (2-1/4 inch strips). Always wished her XL ruler came with a 1/4 inch version. This tip might solve that!
