cut your camo pattern out of newspaper and loosely tape it so it isn't lying flat against the stock and you will get 'feathering' that doesn't stay flat on the stock.I'm curious how to keep the paint from stacking..at the pattern edges..so it all looks like one uniform layer
Decide on your base color and everything should go over the top of it.
If you can keep hard lines from forming in the paint yo will be good to go.
It can be time consuming but it's worth the wait to go slow.
After you finish you can lightly sand to blend any hard lines
