I bought some dylon dye at the fabric store and it says nothing on the package about using a fixer. It simply says "Permanent Fabric Dye" on the label, and directions for dyeing on the back only mention adding salt to the dye bath. Is the fix (soda ash?) mixed in already? Or should I presoak in a soda ash mixture just to be sure? Would it do any harm? I googled for an answer and I found a couple of sites that mention a Dylon fixer that's sold separately, but you'd think the package I have would say something about it if it was needed. 
Help please!
