I didn't go this year (knees uncooperative), but have in the past.
I regard it as the best show I get to see.
Quilters from around the world have submissions
And, the vendors are terrific.
If you've never used a Martelli rotary cutter try it out, and their blades are so much better than Omni etc.
Superior Threads is there so you can try a spool of Bottom Line, if it's new to you. I use it as bobbin thread in all my machines. They sell pre-wound bobbins (I'm lazy) that fit all my Jems, not my Bernina.
Do go - it's worth the $12 entry - Bring a camera too.
