wwK10, that is what I based my numbers off of. (550)
And thanks everyone, it was a long project. I have not run a thread injector for almost 15yrs. Once I got it running correctly and using the "tape the baffles" method instead of pinning them, it went much faster. Oh yeah and the fact that I had to completely take it apart once because I failed to look back at my seams. The thread tension was way off. I had loops instead of nice tight stitches. I have three more pillows, and enough material to make another UQ just like this one. After that I plan on making ether a full length UQ or two more 3/4. I am trying to get my Wife and kids into Hammocking. If I have any down left I want to make one of those cool down hats. Are there any good easy plans for making such a contraption?
