I am familiar with the soft loop and are using it.
Do you glue normal Velcro in or the hard hook stuff like is in late model vehicles?
I have done some like this but find it a huge pain in the butt to cut the channels. It is hard to keep the channels even. I can cut straight lines but can’t cut channels that are the same depth to save my life.
Is there a trick to that ?

My question is based mostly on buckets.
This is what I am working on at the moment. And here is an example from the web.
Most of the time I have cut through the foam and ringed it down.
Not real familiar with using Velcro.
