As far as I can tell, the seam was never made with a folded edge, so the innermost run of stiches only had a few strands of weave to hold them in. It only took 1 “delicates” wash cycle to completely knacker it.
Is there some sort of non-invasive reinforcement that I can glue/iron on to the back of this seam to prevent it disintegrating completely? A quick google shows lots of that tape that you iron inside a hemmed edge…
There used to be two pieces of fabric sewn together with two runs of stitching. Now, there are two very ragged frayed edges, held together by only one line of stitching, and a good tug on either side would probably separate the whole lot.
I’ll get a photo up later.
(That Fraystop glue looks the business, but the right time for applying it was before the fray happened!)
I would try trimming, overlocking and doing another set of stitches. But @StudioNelle knows much more about mending stuff than me and might have better ideas?
It’s already pretty tight on the seat cushion, so I’m wary of making it any smaller.
I was in John Lewis oxford st. yesterday and they have a huge haberdashery dept. I found some iron-on repair tape which looks pretty good. Will report back!
Iron on tape is good for a bit but invariably comes apart in my experience, it’s more useful for holding things in place while you sew them than a long term fix.
