I just discovered I can use image rerolls to change my horse's appearance. But I also found out I just have 10. I used 5 before I realized I was using them all up. Will I get more? Thanks!

You may purchase rerolls under Grow > Misc > Rerolls.

You can purchase more rerolls through the GROW page or with ebs from other members. There are also one or two specific events every year where rerolls are given away, but beyond that, no, you will not get more. They aren't something like ebs where you get a bank stipend every day. They are usually something you need to go out and purchase.

Thanks!
