Hi, These are some of my favorite rulers and favorite tutorials:
http://www.ezquilt.com/tutorials/tutorials.htm . There are fantastic tutorials on all things quilting on YouTube. I especially enjoy the Missouri Quilt Co and Crazy Shortcut Quilts, but the tutorials are really endless. Wish our highspeed was a little faster, but even with the starts and stops they are extremely helpful. Have fun! Best things I've learned for technique: light even pressure, rotary cutter at 90 degrees, careful fabric prep to avoid doglegs, and I love Invisigrip to avoid slippage. Good luck and enjoy!
