Jetprosofstretch: 375* for 30 seconds.
Everlast (Ironall Dark) 375* for 6 seconds.
Check the prices for JPSS in the future at tshirtsupplies.com and new milford paper. Sign up for the newsletters at all the suppliers so you are notified of the sales, they can be excellent (30% off). Tshirtsupplies.com is offering 5% off their already great price for signing up for the newletter.
Good luck to you, hope the shirts come out great.
