My biggest change that I have seen over the years of course are rotary cutters & all of these helpful rulers & gadgets we all have now. Also I used to save my cereal & cracker boxes to make templates for different projects. Also the internet. What did we do before the internet? lol It has opened up so much information on tips, techniques & ideas. Another really big deal to me was finding this board. I never knew another quilter. Nobody in my family ever quilted so when I started quilting I got a lot of my information from library books. (My paternal grandma sewed but never quilted) I took Home-Ec in 7th grade & always loved to sew. Things have really changed since then. lol
