Straight or cross cut rabbit fur, straight cut for the tails, and they are simply called rabbit fur strips, any fly shop will have them. They are quite easy to make.
Wow. Ya $8-$10 is a lot. In Oregon you cam get them for around $4.69 to $6.00. I ordered my own weight mold and just got some rabbit zonker. I need some cross cut still, but I do also have some marabou. Maybe I'll just put maribou for the body and use rabbit zonker for the tail.
