I'm so glad you asked the questions and have enjoyed reading the responses. I have done the muslin on freezer paper (having soaked it in Bubble Jet) and I have used the commercial sheets from JoAnn's. BUT I have had absolutely no luck. I did a quilt putting pictures of my granddaughter in the sashing only to find out when one got wet that the pictures ran. I had to totally disassemble the quilt to get the pictures out. I have an HP printer and i've been told that some printers do better than others. Be sure you test whatever you use so you don't have to do what I did. I'll continue to watch this post and maybe can find an answer to my own problem.
