Large Arched Niche With Rounded / Bull Nosed Edges


This is a very large art niche in the entry I blogged about yesterday. The edges are not just rounded, but the top is arched, as well. Wallpaper might turn the rounded edges alright, but it will not handle the arch and wrap under it, too – at least, not without a whole lot of cuts and splices. Best to trim at the edge and leave the underside of the arch painted.

It’s a whole lot harder than it sounds, because, with the paper hanging over the edge, it’s impossible to see where you are trimming. I have a little gadget (not shown) that is made from the same plastic edging that is used on the drywall to form these rounded corners. It has a couple of notches cut into it at various spots. I place a pencil in a notch and run the gadget around the rounded corner, and that gives me a nice, straight line to use as a guide for trimming.

Personally, I’ll be glad when these bull-nosed edges fall out of style. In the meantime, I am happy I have my little gadget in my toolbox.

    Hi 90 Days. Thanks for reading my blog!
    Read this blog post – it has a picture of the gizmo.

    As mentioned, it is cut from a strip of the plastic molding they use to form these edges on the drywall. A dollar or two at Home Depot. Then you cut notches in it, placed where you want your trim to hit the edge of the rounded edge.
    Some of my friends use their knife right in the notch, and slide the gizmo down the edge and trim that way.
    I find that the thing wobbles too much, plus it’s awkward to hold the blade and the guide at the same time.
    So I put a pencil in the notch and draw a line as I move the guide gizmo down the edge. Then I go back with my razor blade and trim along the pencil line. That way, I can also adjust for any wavy lines or wobbling the guide might have done.
    I hope that is not too confusing, and you will be able to adapt this trick and start getting nice trims on these (dad-blamed) bull-nosed corners.
