I also read all the main threads but I will look at all the pictures on Amazon in a book and see if it suits my needs otherwise my budget would bust! I am always happy to read that someone found a notion that helps them quilt more accurate but I know that if I slow down and sew my seams a little slower I can achieve perfect seam accuracy. I did recently buy a MSQC set of three spools of Aurifil daily deal but just because someone suggested it, didn't get me to go out there a buy a spool. What may work for one quilter may not necessarily work for me.
