I will make a couple of suggestions.

1. Also get a trim iron. They come in VERY handy.

2. If the budget allows, get Coverite irons instead of the Tower irons. The Coverite irons are a lot easier to adjust the temperature on and they hold the temperature substantially closer than other irons.

3. I STRONGLY suggest using Ultracote instead of Monokote. It seems from various reports on this site (and my own experience) that the quality of Monokote has really gone downhill the past couple of years. You will also find Ultracote a lot easier to use, especially if you are new to covering.
