The duvet cover on my bed had a couple of holes in it that were only getting bigger with time. Duvet covers are expensive, and I kind of like this one, so I decided to see if I could patch it.
The most frequent suggestion you run into online for patching things like this is to use fusible interfacing, essentially an iron-on patch. Seemed reasonable but for Charlottetown being sold out of it (now that all the pandemic bread has been baked, are we turning to pandemic patching en masse?).
At Walmart, however, I did find some fabric-patching glue, and decided to try that.
I cut out a piece of similar-looking fabric about an inch larger than each hole, tucked them inside the duvet, and then applied a thin layer of glue. I managed to make something of a mess of things, but, in the end, it all held.
I wasn’t content to leave my patch in the hands of chemistry, so I supplemented the glue with some hand-sewing around the edges. I managed to make something of a mess of things, but, in the end, it all held (I should become a better sewer).
The result isn’t elegant or invisible, but the holes are patched.
