I'm getting ready for my first big painting project, which involves a 5x7ft canvas. I plan to use 2x2s for the frame, but since I don't have any tools, I'll be having them cut at the hardware store and using sandpaper to bevel the edges. I just want a slight bevel to prevent the canvas from getting damaged over time. Can anyone tell me what grit of sandpaper I'd need and how long it might take if two people work on it?

Honestly, if you're strapped for cash, you could consider buying pre-cut stretchers or even reusing old ones. Hardware store 2x2s can be a bit iffy quality-wise, and cutting them might just lead to warping. If you're making your own, check out how real stretchers are constructed—they usually slot together and allow for adjustment.
I hear you! Also, kiln dried wood tends to warp less than regular lumber, so that's something to consider if you're looking for a bit more stability.
For sanding, I’d recommend starting with 80 grit for most of the beveling and then switching to 120 grit to smooth it out at the end. Buying a hand plane for this doesn't really make sense; sandpaper is much more practical for what you need and it's pretty cheap!
A lot of 2x2s from hardware stores usually have rounded corners already, which is great for avoiding sharp edges and splinters. But if you're sanding, keep in mind that sandpaper can wear out quickly. You might want to look into using a chamfer plane instead; it cuts the profile without all the dust and mess.
Totally agree! Making your own stretchers is a great learning experience but can be tough without the right tools. If you're on a budget and just trying to stick to your project, pre-made might be the way to go.
