My house windows have no trim on them (similar to the first picture) and before I paint the house I wanted to explore what it would take to add it, technique, etc. I'd like to add simple square trim (somewhat similar to the second picture, couldn't find a real good one) and I would think that I could take a circular saw and just cut the width of the trim away from the window. But I know that I don't know enough to go with that so my questions: I have wood siding that overlaps (not sure the correct term) so how do I go about cutting it without going into the below wood? When I add the trim do I just caulk between the window and trim and then between the trim and siding or do I need to do more to prevent water damage? Any other tips for a complete rookie? Thanks!

Wasn't really sure what category to put this in, but hopefully someone has a good suggestion for me. We have a playset ([url]http://richmedia.channeladvisor.com/ImageDelivery/imageService?profileId=52000717&imageID=151941562&recipeName=400x400[/url]) that has some very low beams in various places, and the kids are always hitting their heads. The company sells a piece of padding ([url=http://www.gorillaplaysets.com/Swing-Set-Safety-Pad-p/06-1002.htm]Safety Pad for Swing Sets - GorillaPlaysets.com[/url]) but it only works on straight beams (playset only has 1 straight beam, and several curved ones, or straight ones that have another piece of wood attached to them, forming a T). I'm trying to figure out how to add padding to these curved or T section. I'm thinking maybe some sort of foam pipe wrap, wrapped in a tarp and then taped with weatherproof tape? I'm not really sure what else to try. I also want it to be as weatherproof as possible so it doesn't get gross/moldy/etc... and have to be redone all the time. Thank you in advance for any suggestions!
