Hello Moonange12! I have done several reginagrewe PP projects, free ones + have purchased her patterns as well. They are pretty easy to do, especially the one you referred to. I have made this one in different color combinations. I'm making her Mushroom blocks now (also free). Try her Tulips, it is lovely!
(Edit) Have you checked the Thimbleberries way to PP? Google thimbleberries tutorials. You fold the freezer paper, don't sew through it so there's no tearing off the paper which I hate.
