I have a 1920's Brunswick snooker table with leather pocket rims and crocheted drop pockets. The leather that goes around the irons is nice and thick, then turns into thin flanges at the bottom where the knit part is sewed into them. When I hit a ball at a fairly good speed and it goes straight in, it will quite often hit that flange at the bottom of the leather which is rather stiff and acts like a trampoline. The ball comes straight back out onto the table. Is there an easy way to fix this? Thanks!
