I find it helpful to use a thin pressing cloth (I use a plain "floursack tea towel) between your interfacing and the iron. The pressing cloth prevents any residue from the interfacing building up on your iron.
If you use a tricot knit interfacing, be sure to put the knit crossways of the knit on the tee shirt. Knit stretches and if it goes the same direction, it is not very stable. The knit on the tee shirt will be up and down, Put the interfacing sideways.
