I'll try to post pics later this evening but wanted to post an update. The direct method is finished and has been washed, rinsed, and dried NOTE very little color left the area BUT the fabric is much softer which would make it easier to needle or sew with the machine. There are gobs of holes as well on this particular piece, whereas before I applied the baking soda paste there were only hard crusty areas.
The plan is to stabilize the fabric, just like the previous piece, and stitch as usual with my machine. I will embellish the areas around the holes and take it from there.
Have a wonderful New Year Everyone!
