When you're machine sewing a basting stitch, you can raise or lower the upper thread tension until the stitches are almost looping, and this will make the seam extra easy to unpick as one thread will just slide right out when you pull on the end. Just need to remember to set the tension back to normal before sewing your regular seam!
That was a great idea to add interest to a project - can totally see that on a dress or skirt! I was admiring your dress - lovely use of fabric complements and so well constructed. If you made that, it is a super way to advertise your sewing prowess. I enjoy your presentations and see you have lots more I can view in the future!
Oooo I don't have any garments with this but now I will! Maybe along a sleeve or side seam for trousers? I'm trying to think of what would be cool with movement.
