Annie it sounds like you already have some things that work for you so don't let someone else discourage or try and side track you into things that may not work for you. I some times wash, and some times not, use all my machines for piecing (my FW being my favorite) and some for quilting. Never use bias binding unless I have to and enjoy every minute I spend with my quilting hobby. The only two rules FOR ME are...take time to cut accurate and do my best to stay with the 1/4" seam. Find what works for you, and that includes thread, scissors, cutters, blades, cutting matts, machines, needles, patterns, fabric and guilds. Just enjoy the craft as it is supposed to be fun. Welcome
