Lots of times I read instructions for speeding up a process and sometimes that doesn't pan out. For example there are ways to make HSTs where you do many at a time BUT the outside edge puts in on the bias. While I agree with the speed part, I HATE working with those biased edges, even when they are starched well.
Most of my "experiences" usually come from an attempt to speed things up (read: find short cuts) and I pay for them every time. Fortunately for me, I don't repeat the same thing twice, so it is always a NEW joy. lol
One thing amazes me, and ghostrider has already talked about it: As many years as I've been doing this hobby, I still have questions, still learn new skills, still get excited about new methods or new color combinations.
A few truths had to be learned the hard way. I used to think that ironing/pressing was overrated - after all, I hate ironing clothes. After a few pathetic results in the quilting world, I am now a presser. Even if I finger=press, but press I will.
