Here’s one that I do as a matter of course. I don’t think I learned it anywhere, just one day I had an “aha” moment. When using tailor’s tacks, if two different markings are very close, I use different colored threads so I can easily differentiate between them. As an example here, in the Butterick 5250 pants that I just finished, the belt loops sit right next to the darts – almost on top of them. So to make sure I follow the correct markings, I use a different color for the dart than I do for the belt loops. In this case, the dart legs are marked in white thread, and the belt loops in blue. It makes it easier to discern between different pattern markings, and it doesn’t take any more time. Win win!
