[QUOTE=RavenLunaStitch;5988814]I know there are lots of bells and whistles like ergonomic handles, lights, etc., but I'm asking about the business end of a seam ripper. Sharp enough to work well without destroying fabric in the process and one that will last a while. I didn't care much about this until I started taking apart clothing items Bonnie Hunter style for some scrappy quilts. We talk a lot about other favorite tools but I want to know if any of you have found a real winner that you will keep and use for a long time?[/QUOTE
Mine best one came with my machine, left behind by a previous owner, so I don't know what it is called. It looks like a miniature medical instrument. It is thin stainless steel with a curved very sharp edge on the curve. I guess I have had two of them for 20 years and they are still sharp. The best thing about them is that you can slip them into a seam and cut threads without cutting or snagging you fabric. My guess is that they are designed for professional seamstresses, alterations and such since I have never seen them in a fabric store. Someone who does this for a living might be able to help. Eleanor Burns uses her rotary cutter but I would not attempt that.
Thanks to all who tried to help me with FMQ--I haven't come close to mastering the tension thing but at least can make an ugly stitch that does not pucker.
