I would have to say that even though I had made 4 quilts in the last 2 yrs. Everything I know I learned here in the last couple months. Most important to me was a scant 1/4 inch seam. Pressing not ironing. Squaring up blocks and nesting seams. Starching has been a biggy! Applique is coming by reading this board.
I don't know now how I managed to make those 4 without this knowledge. I am forever grateful to the members of this board. I read it every day now.
