I agree with all about getting rid of the mustard color. I personally can rip out seams very quickly, partly from doing it a lot, and also because I use the OLFA point cutter. Once i get the first couple of stitches out it is a matter of holding it on my lap with the outer heel of my right hand, the left pulling upwards on the seam, and my right hand just lightly tapping the open seam (still holding fabric down with heel) with the point cutter. Goes soooo quickly and have never cut through material.
