So im currently using a tri top, and after about 3 months the edges started to curl. This causes the edges to painfully dig into my skin and makes my binder have major rollups. Is there any way I can flatten it out?
Thanks
(P.S this also happened with 997s)

My days of using the tri-top was the same.  Once it stretched out and started to curl, it wouldn't sit right again.  I don't think it can be straightened without actually cutting it and re-seaming it. 

I never wear my tri-top straight down. I double it over, so no curl!
