Cool to see velvet jackets being worn nowadays!

Do you get slippage if you're wearing the velvet Sheriffmuir and using a velvet bag-cover?

Actually it's odd about the velvet bag-covers, I've played them for 40 years and never had a problem with them slipping.

Then a few years ago I got a velvet bag-cover with the Dycem patches, but when I debuted it at a wedding gig I could barely play my pipes! It was the first time I had a bag constantly slipping down. I never wore that cover again.
