I'm with GrammaNan, where to start!! Lol! I have been at this for about six years and I don't think I've made 30 yet. I am still busy with kids at home, though, plus I'm very slow.
Anyway, I still struggle with hst's. I make them big and cut down, but I would really like to get where I can make them perfectly and maybe just sliver trim. I also hate making flying geese with flippy corners. I need to try Eleanor Burns technique.
I'm sure there are plenty of of other techniques that I need work on, but I'll leave the list with just those 2. Gina
