The only thing I did different was, after I got the seam cut completely out, I cut it and soaked it in water and stretched it and worked with it to get it straight. It worked! I tell ya...it's no easy feat taking the baseball apart because it is glued like, somebody may try to rip it off. I bet they never thought a female would rip it apart and make jewelry. It's worth the work so, give it a try!
Love & Peace,
