Hi Ryan

I have done a lot of flocking in the past, now if I want that lined look I'll razor cut Leather, before flocking. When I did flock I found that Donjers adhesive paint a royal PIA. I do use their flock, but if you tried a fair quality or better Acrylic paint, and the Donjers you would never buy the high priced Donjers again. Most craft stores (I use Hobby Lobby) will carry colored Acrylic paint that will match the Donjer colors. When I tried to use their paint I had real trouble getting any color except black to adhere. No problems with the Acrylic. I read of a lot of people who agree, and a lot who just use the Donjer stuff, maybe we are holding our tongues wrong?

One thing for sure to make sure you do. You have made a nice project, and this is about the last step, so don't mess up your hard work, instead just make a smallish bottom, with a side pin nailed to it, and finish that with the flock. Chances are you will back off, and do more practice. Problems can occur first with painting on the adhesive, and this is where the Acrylic will shine, much easier to control, plus it dries a lot faster, with no stink. Then the right amount of flock. A lot suggest just flooding it, let it dry, and shake out the excess. I never found that a good look, so there is a right amount, and until you see it, it's hard to describe, but once you see it, it's like a bike. 

Mike I used a matt cutter, like for picture frames, worked well for me on solid material, plus easier to store than a paper cutter, or I use a rotary cutter on one of the green boards made for them, along a thin ruler, but I can see it working with a sharp blade on the hatchet cutter.

Duck, just plain good to see you typing here. Be Well
