For the last 25 years or so, I've used old sheets with targets spraypainted on them.
The original reason was because the paint didnt break.... and I'd reuse them because I was poor back then.
Not an issue these days. In fact, I always seem to have a case or 2 of some fields "field paint" that I have no use for. But the wife has a fit if she can see -any- paint splatter marks on trees. "Makes the property look trashy". SO... the sheet method keeps her happy.
