Just got myself a macro kit for my Lensbaby, so all I need now are some flowers and some of your talent
Cheers

Have fun with those closeup filters, they really work well, as I discovered with the ones that came with my Lensbaby Sol 45. I can use mine not only with the LB but also I saw additional possibilities and promptly got a step-down ring and also can use them with my Sony 50mm f/2.8 macro, which I've done a couple of times.
As for subject matter, macro and closeups don't always have to be of just flowers or insects.....look around, find some interesting object in your house and experiment with it. Make the ordinary look extraordinary, create an abstract out of just a section of it, or surround it with interesting props..... Grab something out of the fridge or out of the bowl of fruit on the table and see what you can do with that, too. Have fun with your new tools!
