Wow Platyhiker! Thank you for taking the time to write such a thorough answer - I'm definitely trying this! I'm also guilty of the 'wobbly seam' on occasion (despite having watched many videos I think it's practice practice practice I need now), so that's an added bonus. I will absolutely try this and report back. It's going to be a great use of the 8" ruler I have but never used since I bought the 12"...
Yes, luckily my pattern has me cutting oversized squares - phew! I need to trim to 4 and 5/8". I am definitely marking the ruler for that one.
