I bought a seam ripper thing made by Martelli. I forgot how to use it, so asked at their booth the next time I went to a show. Watched her use it numerous times and then have promptly forgotten how again. I too bought a plastic cone holder. After struggling with trying to use it and have it move around while trying to get the thread to come off it and into my machine, I gave up, threw it away and ordered a heavy metal one, which I use almost everyday. Another thing is probably the most expensive thing is an Easy Quilter 3.1 & Tracking System. I used it once and just couldn't get the hang of moving the machine instead of the quilt when fmq. I also didn't like only being able to stitch in a small row and all the extra fabric and batting you had to have for the edges and to wind on the rollers. I do have some rulers I've never used, but someday I will use them. I bought a couple diamond rulers 10+ years ago and just used them a few months ago for the first time. You never know. I'm also a sucker for buying books and then deciding I don't like the pattern once I can read all about it. I probably liked the fabric colors, in the first place, and that's what made me want the book.
