So I have a window that doesn't have trim around it (see pic 1). And will eventually need to make a trim around it that matches the other windows in the house (see pic 2). The trim does not seem complicated (it's an old house over 100 years old). I have a miter saw and a circular saw. But some stuff on the trim that I need to replicate looks to be L-shaped legth-wise. I'm assuming that to make an L-shaped piece of wood I'll need a table saw, a I right?

Also, I don't know whether it be better to buy a table saw and try to do it myself or to find a professional to do it for me. While I do have future construction projects in mind I don't think any of them will require a table saw. So idk. Maybe I could rent one? Still, I might spend more $ and ruined wood + time than I would on just hiring someone who knows what they're doing. Idk
