Yes, no instructions. Thats why I started this thread. I have found on the web that some are tacking at 220F and shrinking at 300F. But, like Turbojoe above, it doesnt seem like it tacks all that great at 220F so I have been practicing tacking at 250-300F also. 300 seems to work well and I am getting the hang of moving the iron around. I am going to start covering my T-Craft this weekend and will probabaly try tacking at 250-275 and final shrink at 300-325 and also use the heat gun on open areas. I happen to have an infrared temp gun to check temps.
