I saw that one and while I think it is absolutely adorable, unfortunately $30 is way too much for me.
I will say I have spent that much on very intricate patterns (judy niemeyer, etc) that have come with the paper pieces.
I wonder if she marks it up that much just because she then has to discount it for wholesale, etc? And to keep the price even for anyone paying for it, she has to sell it at that price too? I know when I was sellling scrapbooking paper piecings, I wholesaled to one store and honestly took a large loss so they could afford to resell them. Because there was no way someone was going to pay 200% of what I normally charged. I did okay as she bought a lot and that helped because I could do more of a mass production, but I still made less than my time plus expenses.
Honestly I love her patterns, but have yet to buy one.
