Because I can't be outdone totally by Moose , I kept poking my sample with the size 0 US/2mm DP. I did actually get through the fabric. Not. Easy. I really had to work to do it, and I think that means that it will rarely happen if ever in actual use.
Darcy, I hope you keep a large supply of fresh sewing needles for your incredible sewers there at TB.
What I thought was VERY cool-- that rubberized stuff seems to be self-healing/self-sealing. It's really hard to tell where the DP poked through on either side of the swatch fabric.
And the cat hair? Seems to fall off the outside of the fabric fairly quickly. Not as quickly as the "inside"-- probably because of texture, but pretty quickly.
Moose, can't wait to hear the woodchipper report...
