I'm thinking a lighter hand on the dyes, more ice to the layer, and watch out for the red and darker colors......very light on them. And watch your color combinations.
This last group looks a little better in person. I also think the weight of the fabric has played a part in this. I used a cotton silk blend on some of these which may have caused the dye to take faster. I do have some really nice ones I love that I will save for the reveal this coming Friday!!
