I'm not sure what you mean by "It won't cover completely."

Do you mean not enough material, or that it might be a bit translucent?

Is is actual Monocote that you have, or are you using the term generically for the covering material?

I'm guessing that you mean it's translucent. Some of the lighter materials will be a bit translucent, so they will let some or a lot of the wood grain show through. Don't worry about that. Depending on what color you have, some colors end up more translucent than others.

The covering gives you a color layer and adds a bit of strength to the finished model. No need to do two layers if some wood grain shows through, you'll just be adding weight to the model and no benefit.

There's no need to tape the first piece. Just get the piece lined up and tack down an edge. Slowly stretch and work out from there along the surface until you're done with that side. It's no different from ironing a piece of clothing. Leave a bit overlapping over the edge and tack that down before doing the next side. You'll have the hang of it in no time. Just avoid having too hot of an iron. Not enough heat is better than too much.

What brand is the covering you're using? It can help to know that.

And please, don't apologize for being a newbie. It's what these forums are all about. It wasn't so long ago that I was aking some real basic questions and it was through these threads that I learned a lot about the hobby. Before too long you'll be helping a newer flyer out and that's how the hobby grows and spreads ... and improves! \

Enjoy!
