I love ruler work so I always look for a new ruler when I go to shows. By far, my favorite one when I first started out (and still a favorite go-to) is the VersaTool by HQ. It's a neat little ruler with a straight edge for SID, a 90 degree for corners or chevrons, a half-circle arc and another broader curve. It has etched lines to help with placement and 2 little indents for the hopping foot to use for outlining applique. Can you tell I love this little ruler? Also, if you need thread, be sure to visit the Superior Threads booth. They'll have their entire line in various colors. Enjoy your trip. Wish I was going.
