My local quilt shop is sponsoring a Farmer's Wife Club and at the first meeting recommended some notions that might be helpful. I've already mentioned here that I hope each meeting isn't only a marketing opportunity, but I have found some things very helpful!
Forked quilting pins: very fine gauge, two-pronged pins that hold seams open while you sew. A bit slippery and you have to have pretty good coordination to get them in place, but ... I like them!
Here's a link so you can see how they come. I got them with 25% off at my LQS, but got several things at the same time so not sure what they cost.

The Purple Thing is also my friend. My machine balks at heavy seams so this helps push it right through. There are many other uses for this handy little thing. Here it is

A friend came over to mark a quilt with me. She uses 3 yardsticks taped together to mark the long diagonals for cross hatching. My husband came up with a long aluminum thingy from the hardware store. I'm not sure what it's supposed to be for, but it sure does the job. You lay it across your sandwiched quilt diagonally, mark the line with chalk, then go to the other diagonal and do the same. I tuck it behind a cabinet when not in use.
