Tip of the Day: Post-It Notes
I was watching a Craftsy course with Eileen Roche, and she gave the most awesome tip: use post-it notes as a cloth guide. You just take the bottom note off a pad of post-its and stick the whole pad to your needle plate at whatever distance you need from the needle. (sticky edge closest to the needle of course)
I just tried this out while stitching the channels for a drawstring on a bag and it was pretty awesome, I didn't even have to mark the fabric. I just put the needle down where I needed it, stuck the post-its at the edge of the fabric, hit the start button, and let it go. I just had to do some minimal guidance of the fabric to keep it in line with the edge of the post-its... came out perfectly!
