I was making a whole bunch of aprons that were all the same size. Instead of having to measure each one for the cutting I cut out a piece of muslin the size I needed and wrote on the pieces what they were. I then lightly sprayed with 505 spray and when I use the pieces I just smoothe the "pattern" over my fabric and I cut it out much much quicker than if I have measure every one. The 505 makes it sticky enough that it will not shift on me but is easily removed and used over and over again.
