I'm wanting to experiment with some LWI and also some shibori pole wrapping techniques on silk. I thought a fun use of the experiments might be children's playsilks. I am wondering if I should go with jacquard acid dyes in my microwave or procion dyes, either with vinegar or soda ash? I'm not too concerned about color shift since they are for play. And they are not for babies, but as they are for play, I suppose there is the possibility of them being put in the mouth...toddlers are weird sometimes LOL, so safety is a consideration.
Also, has anyone used the cheap playsilks from dharma? I guess I will just have to order some, but was wondering if anyone had used them before.
