Both boards worked well for the fabric. I like the foam better. I could cut it myself and work the sizes both for the large boards and the fat qtr. I like the price much better too. I don't mind paying a fair price, and the $35 is a fair price for the plastic which I got at a local sign shop. But I need to save pennies where I can and I couldn't beat the price of $10 for 60 boards over the $35.
I had found one of those Fabric Organizers at Hobby Lobby last year for $1.00. But I wasn't willing to spend $100 on what I thought at the time were "those silly little plastic boards". And when the I saw a thread here on someone finding their own plastic and doing their own. I thought I could do that too. And did. Ta DA!
