I am thinking of using velcro for the left hip fastening instead of the buckle and strap.
The fuzzy portion attached to the outer apron and pleats on the inside (wrong side) and the hook portion attached to the end of the inner apron. If I make the fuzzy side a bit longer than the hook side to allow for more waist adjustment, do you think the hook portion of the velcro will ruin the 13 oz wool tartan when putting on and taking off the kilt?
This would also allow the "button hole" to be sewn up as well, reducing the stress on that area.
There is currently heavy canvas installed per Robert MacDonald videos, and I can easily close the hole up by continuing the lacing stitches.

I did a bit of experimentation with the tartan fabric over the last day pushing the velcro hook against it and peeling back. The tartan fabric does not seem to catch on the hooks.

Your experience and thoughts would be greatly appreciated!
