Lots of fun, new notions out there, but I always want a new seam ripper each year (guess that means I make lots of mistakes!), new rotary cutter blades, some great snips(I leave a pair at the ironing board, at the sewing machine, at the long arm, at the cutting table) some new pins if I'm finding many that don't slide well anymore.
I also love my Accuquilt GoBig so would invest in a couple of new dies or cutting mats; like having a rotating small cutting mat to take to classes. I also like having a travel sewing kit--scissors,stiletto, thimbles, thread,pins, snip,pencil, etc to "grab & take" when I go to classes.
