I have not tried LWI yet. Maybe I'll give it a go sometime this week. I have some dye left over from Friday that I'm trying to use up before it goes off
I have lots of dye left over from previous projects, and used some for LWI dyeing this weekend. Here are 2 pieces that I particularly like:

I'm not sure how old the dyes were that I used, but with LWI, even if they come out faded or pale, you can always overdye. In these cases, I love the 'marbleized' look I got from the first dye bath, so didn't do any overdyeing. And my back doesn't hurt...
