- 100% agree on contour gauges being more trouble than they’re worth with old plaster or uneven trim. They just don’t flex enough for those weird bumps.
- Cardboard’s my go-to, but I’ve actually had decent luck with kraft paper for tight arches—just tape it in place and run a pencil along the edge. It’ll wrinkle a bit, but you get a cleaner line.
-
—Smart move. I learned that one the hard way after wasting a pricey piece of oak on a lopsided arch years back.“tracing the outline, then flipping the template over to double-check for symmetry before cutting anything expensive”
- For really complex shapes, I use a combo: kraft paper for the curve, cardboard for the main body. Tape them together and you’ve got a flexible but sturdy template.
- One tip: if you’re working solo, use painter’s tape to hold your template in place while you trace. Masking tape can pull paint or fibers, especially on older walls.
- Never tried freezer paper, but now I’m curious. Might be easier to get into those tight corners than cardboard.
- Digital measuring tools are tempting, but unless your trim is brand new and perfectly square, they’re usually more hassle than help. Sometimes old-school is just simpler.
Funny you mention freezer paper—gave that a shot once when I was dealing with a weird half-moon window in the attic. It actually held its shape better than I expected and was easier to cut than cardboard for those tight inside curves. Still, I’m with you on digital tools. Tried one of those laser measuring apps last winter, and it got thrown off by every bit of wonky plaster.
Couldn’t agree more there. For me, nothing beats tracing with kraft paper and a steady hand, especially in these old houses where nothing’s ever quite square.“Sometimes old-school is just simpler.”
- Ran into a similar mess with an eyebrow window in our old place—nothing standard about it.
- Tried cardboard first, but it kept buckling at the curve. Freezer paper, like you mentioned, worked better than expected. Never thought I’d be raiding the kitchen for home repair supplies, but here we are.
- Digital measuring tools are hit or miss for me too. The app I tried couldn’t handle the lumpy plaster and weird angles—numbers were all over the place.
- I keep coming back to tracing with kraft or butcher paper. Lay it right up against the frame, mark everything out, then double-check with a tape measure before cutting anything expensive.
- Only thing I’ll add: sometimes I use painter’s tape to hold the template in place while tracing, especially if I’m working solo or on a ladder. Saves a lot of swearing.
- Old houses definitely keep you humble—there’s always some surprise behind every wall or window... but that’s half the fun, right?
Freezer paper, huh? That’s a new one for me, but it makes sense—never thought I’d be using kitchen stuff for window projects either. I’ve always defaulted to kraft paper or old wrapping paper rolls for templates, but sometimes it’s a pain getting it to stay put, especially if there’s a breeze coming through. Painter’s tape is my go-to for keeping things from sliding around too, though I’ll admit I’ve had it peel up some old paint here and there.
I totally hear you on digital tools. I bought one of those laser measure gadgets thinking it would be a game-changer, but our plaster walls are so wavy it just spits out numbers that make zero sense. Ended up trusting my tape measure and eyeballing more than I care to admit.
One thing I’ve wondered—has anyone tried using that flexible curve ruler stuff? The kind artists use for drawing odd shapes? I saw someone use it to trace the curve of an archway and then transfer it to plywood. Looked like it saved some headaches, but not sure if it’d work for bigger windows or just smaller trim jobs.
Old houses are definitely full of surprises. Last year when we redid a bedroom window, we found an empty hornet’s nest tucked in the frame and some weird newspaper from the 1940s used as insulation. Made me laugh, but also reminded me nothing is ever straightforward in these places.
Curious if anyone’s found a trick for getting measurements right when the molding isn’t even the same on both sides. Sometimes one side of the arch is just... off by half an inch compared to the other. Do you split the difference, or just pick a side and hope for the best?
I know a lot of people like to split the difference when things aren’t symmetrical, but honestly, I just pick the side that’s more square and run with it. Otherwise, I feel like you wind up with two sides that look off instead of just one. The flexible curve ruler is a cool idea, but I tried it once on a big window and it flopped around too much—ended up going back to cardboard templates. Sometimes old-school just works better.

Yeah, I hear you on the floppy ruler. I bought one of those thinking I was about to revolutionize my window game, but it was basically a sad noodle by the time I got it up to the arch. Cardboard templates might not be fancy, but at least they don’t try to escape halfway through tracing.
I’m with you on picking the more “square” side, too. That whole “split the difference” thing sounds good in theory, but when you’re standing back looking at it, you just end up with two sides that are both a little bit wrong. I’d rather have one side that looks intentional and one that’s just...well, a little off. Honestly, most people won’t notice unless they’re the type who brings a level to dinner parties.
Here’s a trick I picked up from my neighbor (he’s a retired carpenter and has opinions about everything): blue painter’s tape. If you’re doing an arch or triangle, run strips of tape along the edge of the glass, then sketch your line right on the tape. You can tweak it until it looks right, then peel the tape off and slap it on your cardboard for a template. It’s kind of a hybrid old-school/new-school thing, and it’s saved me from having to cut five versions out of cereal boxes.
I’ve also tried that tracing paper stuff, but unless you’ve got a third hand, it’s just not worth the hassle. Cardboard holds its shape, and if you mess up, who cares? Grab another Amazon box and try again.
Anyway, just wanted to chime in because I’ve definitely wrestled with all these “precision” tools that end up being more trouble than they’re worth. Sometimes the simple stuff wins.
Painter’s tape is underrated for stuff like this. I did something similar when I had to fit a weird trapezoid window in our attic—ran tape, sketched the line, then transferred it to cardboard. Tried using tracing paper and it just slid everywhere. Cardboard’s sturdy enough that you can actually test-fit it a few times without it getting all floppy or torn. The only downside is if your window’s really high up, balancing everything gets a little sketchy... but tape plus cardboard has worked way better for me than any of those bendy rulers or “precision” gadgets.

Yeah, cardboard templates are a lifesaver for odd shapes. I’ve tried those “contour gauge” tools and honestly, they’re more trouble than they’re worth—never seem to match the real curve, especially on old plaster. One trick I picked up: use hot glue to tack the cardboard pieces together if your window’s got multiple angles. Ever tried making a template for an arched window? Curious if anyone’s found a way to keep the center point accurate when you’re working solo.
Hot glue is a smart move—I’ve only used tape and it always peels off at the worst time. When I tried to template an arched window by myself, I ended up using a string tacked to the center point and kind of swinging it like a compass. It was fiddly, but it worked well enough for getting the curve right. Definitely not perfect, but better than freehanding. Honestly, working solo just means accepting a little bit of “close enough” sometimes.
That string compass trick brings back memories... I tried something similar with a cardboard template when I tackled the weird triangle window in our stairwell. I traced the shape by pressing the cardboard into the frame and just sort of marked it with a pencil. Not the most scientific approach, but it got me close enough for a blackout shade. I totally get what you mean about solo projects—sometimes “good enough” is really all you need, especially when no one else is going to notice those tiny gaps except you.
