Bimini straps

My bimini didn't come with straps to allow it to hang properly from the tower (from one mount point vs all four) when it is stowed. I have been using my daughters old belts which I need to replace. What kind of straps does everyone use to do this? Some appear to be velcro type if I am looking at the pictures correctly. Where should I get these?

Mine are like the straps on life vests. Plastic clips on a nylon strap. Pull on the tail to tighten.

If you have a couple of the old orange basic life vests those would work.
