Reddit mentions of CAP Barbell 12-Piece Puzzle Mat, 12 x 12 x 1/2-Inch

I use this mat and this steamer. You can buy a blocking mat anywhere online but the puzzle mat is the exact same thing and it's much cheaper. I steam block all my acrylics with the hand steamer and for my wool I just get it wet in the sink with cold water, pat out the excess, and then pin onto the blocking mat and let dry.

I use interlocking mats, whenever I need to put it up, I can take apart the chunks and stack them into a 1ft cube! They are already no-slip so they work pretty well to hold the pieces.

• Mats like these for your playspace.
  
  
• Future prescription lenses you put over the standard ones so you don't need your glasses. (VR Lenslab should have that covered)

The mats you linked to are made from EVA foam not PVC.

You can find it used in exercise mats like this if you are going for thick stuff.

If you want it thinner you can also get it like this

Thank you! This is what I used to block - it was pretty easy (my first time using wires, but definitely not my last).

Mats - http://www.amazon.com/gp/product/B00GNAGRKI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 (much cheaper than designated "knitting" ones)

Wires - http://www.amazon.com/gp/product/B001JSQZ88/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 (I think there is a smaller set available, too)

Theyre pretty spongy. I bought them from Amazon, you can find them here. I must say my cats have already torn holes in the mats with their back claws, so theyre not as durable as I hoped.

edit: I'll probably go with the horse stall mats here in a couple months.
