I think a lot of players would need something bigger than a 3’x5’ rug, like at least one that is 4’ or deeper. I’ve always had 4’x6’ rugs and could easily see the need for a 5’x7’ come up with larger kits.I like the looks of an old oriental carpet under drums, but they can be heavy, dirty, slippery, and not nice outdoors in wet weather.
For a drum rug, you can't beat an Enviroback Charcoal 60 in. x 36 in. Recycled Rubber/Thermoplastic Rib Door Mat $21.97
It's durable, it's cleanable, it prevents slippage of drums and hardware, it's not particularly heavy, it's not distracting (no odd colors or patterns), it's made of recycled materials, and it has no drum company's logo on it (which, if it did, would cost you money for their advertising).
It seemed my local Home Depot was hiding these mats so people would buy one of the more expensive ones displayed eye-level. But the online site showed nearly 100 of them in stock. Had to ask an employee to use a lift to get one for me from a pallet of them located high-up on the steel display system.
My Canopus Bop kit and lightweight hardware (but for my throne) fits on it fine. I've used it on turf, wood decking, concrete, and gravel. I have a braided red cord that I use to secure it in a roll for easy transporting.
I bought my knock of Persian for $25 from some dude selling them out of his van on the side of the road. I've had mine for 20+ years, and played hundreds of gigs and rehearsals with it. And yes I still have it.Thrift Store for knock off Persians and the like. Even Target and such....
Buying a drum rug from a drum mfg is ricockulous imho. Hell, why not have it work AND look cool?
