Hanging Lights on Awning

We are the proud new owners of a '97 2518 and we just went through our first shake-down cruise in the driveway last weekend. The kids (3&5) loved it.

I'm wanting to find out the best way to hang decorative lights on our awning. We've got two 5ft sections that we want to hang across the main beam of the awning.

I noticed that there are small tabs built into a slot on the cover, but I didn't really see a way to attach anything to them. I tried some of the clips that we use on the house for Christmas, but do not feel these will properly support the lights that we have.

I do not want to tape these up and I'd like it to be simple enough for the family to do while I'm setting other things up.

Any suggestions?
