I saw this great plan for marking your quilts for FMQ. Trace the design on Press and Seal using a Sharpie. Stick the plastic to the top and stitch away. As long as the sewing isn't too dense it will tear away nicely. Probably one of the biggest advantages is that you can really see the quilting pattern on the top without having to erase your mistakes. The plastic can easily be moved around to make sure the placement is good.
So, that is what I did for my project quilting piece. I drew out my feathers. I traced them forward and backward onto the press and seal. I placed it on the top. I like what I have come up with so far. I am all ready to quilt.
Fortunately, I am not at all confident in my skills so I did a test piece. Worked like a charm. The film didn't interfere with the sewing. It didn't shift around. Except for some tension problems I was able to follow the pattern without making too many mistakes. Even better, it came right off after I was finished sewing. Well all but the color left behind on the thread.
You can see it even better in this image I've altered to have greater contrast. A lovely orange smear on much of the thread. This was NOT a design element I want to include in my project. Now I need to come up with a different marking plan, perhaps the wide orange sharpie was too much ink. Perhaps it would be better if it dried longer. Perhaps a very fine sharpie or a prisma color would bleed less.
