As I thought I might, I lost a bit of steam with the scarf attempt. It's so long and takes up so much thread, and I'm still not convinced it will turn out as I'd hoped. I wanted to see if what I'd done so far would be okay, so I sewed back and forth horizontally about 3 inches up from one end, then cut between those sewing lines. I soaked the small piece in some very warm water and the H20 Gone (again, bought from Fabricland), dissolved almost instantly, although there is enough left in the piece to make it fairly stiff. I imagine with more rinsing and perhaps a dab of gentle soap this would all come out. However, here it isAnd again - doesn't it look like some kind of jellyfish?
And again - rather stiff. I think it would lend itself well to being included in some sort of wall hanging.It seems to be okay, so I will continue on with it and see what happens.
