Interesting to see some slightly 'worn-in' ones. All the ones I have just stay sat in a box out of harms way
What have they been through? Anyone put one in the wash?
Yes all patches come with velcro backing (plus the other bit to put on your kit if you desire), it doesn't add much to the thickness if you'd rather just sew it straight on.
With regards to 40-50, it'd be you guys that see the gain, if we shift that amount we might be looking at a forum upgrade and a new (better) look, colours wouldn't be changed too much just a freshen up. All depends on what we can pull in though.
