Pre cut patch for tc renegades

Looking for the pre cut round ball patch I need for a 50 & 54 cal. Renegades . I have listened to Idaho lewis video on loading and  he is saying his ( the yellow one ) is   What  ?   I think he saying it's pocket something but can't make out what he is saying on my phone.

Found it by chance in a old post.lol
Cotton Drill

I ordered couple yds of the cotton Drill , shot it today in a tc  54, & 32 cal ,  not much diff at 50 yds but was definitely a improvement on the 54 cal at 100 yds
