Thanks, I hadn't considered the snagging issue.

I know the backing you are talking about and may have some of those backings lying around with tie tacks I no longer use - but using the pin may be a problem. There may not be enough material to set in epoxy.

Speaking of epoxy, that may be the solution.

Just put a big glob of epoxy on the arrowhead to set the bar pin backing even with the tine.
