Patterns, seam rippers, rotary blades and having to go back to the store to get just enough fabric to finish a project because my brain shorted out when I was buying the first time.

Backing fabric. If you buy backing of a good quality, it's expensive. But to buy cheap fabrics to use as backing is in my mind a waste of all the hours of work I've spend making the top and will spend quilting it, because the backing will wear so much faster than the top! I want to get as much use out of the back as the top of the quilt, especially for quilts that are meant to be used (i.e. not wall hangings), so expensive fabric it is...

Patterns, rotary blades and batting. Fabric as stash, I can't buy ahead unless I have a project in mind. And needle threaders because I hate to admit that I'm old enough to have problems with seeing up close. I do wear readers but I so miss how well I could see when I was younger.

I agree with rotary blades, scissors (why is a pair of scissors $20.00 or more!) and I lose those pesky seam rippers all the time (maybe that is a sign I don't need them!). Also, I can't justify the costs of patterns. I haven't bought one yet because I was given one at Christmas and to be honest I don't know if I am just an idiot or what but I have no idea how to read the directions! No problems with the free patterns I have downloaded though! I'll stick with free!

I get tired of buying seam rippers. Mine always seem to grow legs and run away. Probably because they feel like they're being overused. lol

Modern patterns and modern pattern books. I'm just not into modern. And if I ever want to do a modern quilt there are plenty in the magazines I get.

I think mine is needles and rotary blades.

I hate to buy threat. Back in the 70's I had a quilt shop. The small spools of thread was 10 cents. One lady came by and would not buy it because 8 miles away she could get it for 9 cents. I remember that so well it really hurts when I have to pay $13. for a spool. Oh yes the one now is much bigger but the memory lingers.

Rulers...especially ones you will use very seldom use.

What I hate buying I; going on an expensive course and being told you need this special,
Usually ruler to do the project. Sometimes I have the ruler at home and now I have 2.
