Giving paper piecing another try...

I have a question on the paper. I have some paper from MS freezer sheets. Any reason why I can't use them and what side do I print on?

The Precision Piecing with Norah McMeeking is pretty good also. I think the Carol Doan class was on sale over the weekend. I'm taking a couple classes and I have so many projects going that I don't know where to go next. But that's the best way for me. I like a challenge.

Unfortunately, my contest pieces are sitting there staring at me.
