Thanks guys.
That wood is knots cut or punched out of a bunch of pine boards from Lowe's. The green is actually some stuff from the company that makes my gold and silver leaf. It was at Michael's over by the stamping supplies, so I gave it a try. Not bad. Gives a "sandy" visual texture which is different. Takes a lot, though.
The kit was the only sierra based one I had on hand. You'd think I'd plan better, wouldn't ya? :wink:
