I finally found some foam mats, not for kids to play on (though if I did have someone over with young children these might come in useful) but for pinning my knitting out. I don’t block everything but the towel and sewing pin combination were not ideal. Now I have my T pins and this huge drying area at my disposal, I am ready for anything!
$20.97 plus tax at ToysRUs.
I forgot about these foam mats, thanks for the reminder, I think I still have them. Will dig them up the next time I need to block something.
