My project for course: Visible Mending: Colorful Knitwear Repair

My final project would have been a sweater, had things gone better. I found an old sweater in my drawer that I'd forgotten about, with 3 holes in it. It was a fine-gauge, store-bought sweater, but I'd mended one like that for the first exercise and I thought I could handle it. Beginner's luck, I suppose. This mend attempt turned out badly. The weave was too loose and too big and I hated the result. I knew I would never want to look at that sweater again, so I gave it to a thrift shop.
For that reason, my final project is a couch.

Sorry it's a bit blurry. This is a corduroy-covered couch that has worn spots and tears we've been living with for a long time. We didn't want to send it to the landfill when it's structurally just fine. We threw a duvet cover over the back, but that didn't hide the rip in the arm, which had a good bit of foam poking out.
So when my husband suggested I mend that, I thought, great idea.
I used Mission Falls 1824 cotton yarn, which I'd had sitting in my stash for years. Unfortunately, the company doesn't exist anymore. It's a worsted weight with an interesting bobbly quality created by wrapping roving in a thin strand. It worked really well at making a thick, sturdy weave that held the foam in place. I had to keeping poking the foam back into the arm as I worked.
Following the arm, I wanted to mend the flaws that had developed in the fabric at one of the seams. But when I threw back the duvet cover, I discovered a whole new gash, over nine inches long! I hadn't known it was there, but it gave me more opportunity to practice.
I decided to work on the gash first. Because it was so long, I stitched it together with sewing thread every two inches or so.

As shown in the picture, I made this decision after I'd already started weaving, which was a little awkward.
I started out using purple for the warp and pink for the weft. Since the gash was so long, I decided it would be boring to do the whole thing that way, and did the middle bit in all purple.
For the frayed fabric at the seam, I alternated colours.

You may be wondering: where did I put the ends? Most of them I tucked under the weave, sometimes with a knot in the hope that that would prevent them from coming back out. When there was a fold, such as with the arm, I sometimes tied them with square knots, trusting the fold to hide them.
I'm happy with how it's turned out. The couch looks better than it ever did, IMO, and makes up for any sadness over the sweater failure. At some point in the future, I'd like to patch a couple of balding spots with sashiko. I've been researching sashiko and there's a special thread for it, but you can also use Pearl cotton thread size 8. So I'm going to buy some. One video I watched claimed that the right kind of thread merges with the fabric over time and makes a stronger mend, which embroidery floss with its multiple little threads doesn't do.
