You are definitely not alone. Although I have never been diagnosed with anything, I was told as a teenager that I had "hints" of OCD. No, I don't need to constantly count things or lock and unlock my doors a certain number of times, but when I do something it has to be done perfectly or else I get frustrated. For example, my house is always clean, but it takes me twice as long to clean it because everything has to be done a certain way. I won't even let my husband do the laundry because he'll do it "wrong" (not that he's complaining
). Anyway, when it comes to sewing, it takes me a while to finish things too. I have found that the estimated time they give to complete a project means nothing. I have never finished a project that has been made from a pattern in the time they say it should take. I have however finished a lot of projects that I have made from tutorials here on craftster and some blogs in the estimated time they give. I have also found those to be more thorough and realistic. Here are a few things that I do to keep myself sane. I ALWAYS read the instructions for a pattern or tutorial all the way through at least twice before I do anything else. I always buy extra yardage (not too much just 1/2 a yard to 2 depending on what I'm making). If it's something I've never made before or there might be fitting problems I make a muslin. Also, I never cut any of my patterns. I trace the size I need onto swedish tracing paper. You can make your alterations directly on the swedish tracing paper and you can baste it to try it on. If it is a patten I use a lot I make a cardboard pattern. You can find a tutorial for that here http://nicolemdesign.blogspot.com/2008/09/everlasting-patterns-fashion-industry.html
. I think you'll find that most of us have unfinished projects hanging around. And anyone who has been sewing for a while has a stockpile of fabric. I few years ago I found a blog where this woman talked about using coroplast, the stuff they use to make plastic signs, to make fabric cards. You cut the coroplast to the size you need and fold your fabric so that you can wrap it around the card like they do at the fabric store. Here is a picture of the end result http://www.quiltingboard.com/attachments/links-resources-f4/14711d1266624000-attachment-14711.jpe
. I got a box of fifty 12"x12" coroplast tiles from ebay a few years ago for $35. I cut them in half for the bigger cuts of fabric and in quarters for smaller cuts. It keeps everything nice and organized and preserves my sanity. I hope you find some of these tips useful.
