A tip for you to minimize/eliminate air bubbles over solid surfaces.

After you LIGHTLY tack the covering (I use 4 tacks ), start in the MIDDLE of the covering, release the tack on one end, and while holding the covering taut, iron from the middle toward the end and/or outside edges.

This takes a little practice, however once youget the hand of it, covering is easy and has few, if any bubbles in the end result.

You will like Ultracote. It goes on easily AND at a lower temperature than Monokote.

If you don't have a thermometer for the iron, I strongly suggest getting one. Coverite makes them and they run about $5.00 from Tower

It makes life substantially easier. I suggest starting with the temperature you need for tacking and once set, mark the setting on the top of the iron with a magic marker (Sharpie ). Repeat this for the ironing temperature and again for the shrinking temperature.

Remember this - all your coverings have a maximum amount of shrinkage and EVERY TIME you reshrink the covering you need to use a higher temperature thab you did before. So try to do your shrinking at the lowest possible temperature so you can reshrink it if/when wrinkles occur.
