I came to QB having quilted a bit but not a whole lot. I took a couple technique classes but mostly just worked on my own. Starching fabric before cutting and sewing has been one of the most helpful things I've learned. Also using washable glue stick to get the corners/points to match is sooooo helpful.
I would also recommend joining a guild. I just joined one last fall and the camaraderie and amazing talent in the guild is just wonderful. I'm looking forward to attending more of their workshops and bees.
