Custom cross stitch backpack repair

Hi Tildes, I would like to share a DIY backpack repair I recently completed.

I have had the LTT backpack since it was launched. It has been incredibly durable, but I have used it so much that some parts wearing out is to be expected. I got one of the zipper replaced through the warranty, but the bottom of the back side was wearing out too. Here is a picture showing the damage. The white fabric sticking out is some internal padding. The stitching didn't come out, the black fabric just wore down enough to start disintegrating. Right after that picture, I secured the worn edge with a simple whip stitch to prevent it from falling apart more.

I considered a few different repair methods, but nothing seemed too appealing. I considered trying to learn how to darn for this repair, but I thought that I wouldn't like the edges of the darn patch. Also, the fabric in that area was so thin that I didn't think it would hold a direct darn repair. I also got a quote from a local repair shop, but they wanted to just cover the area with a new piece of fabric, which wouldn't have looked good.

Around this same time, I bought myself a cross stitch kit for Christmas, to pass the time on the many train trips I was taking. I got quite interested in the hobby, and that got me thinking: maybe I could make a cross stitch repair? Cross stitch isn't very durable, or used for repair, but if it only lasted a few months, it would at least be a fun project.

At first, I was looking into simple cross stitch border patterns like this one. I ruled those out simply because most would have been too tall for the repair I was hoping for. I also liked the idea of creating my own pattern. Since it was an LTT backpack, I wanted to keep with the tech theme. I was also inspired by the dbrand circuit board pattern that was released around the time I started this project. I liked how it evoked the design of a functional circuit board. So I decided to make my own cross stitch pattern.

I eventually came up with this pattern. I liked the idea of the central chip being rotated 45 degrees, since many geometric cross stitch patterns focus on 90 degree angles. I also wanted some different symmetries in different places. The traces connected to the central chip are rotationally symmetric, then a dissimilar patch, and then mirror symmetry traces after that, and dissimilar edges. The left side was meant to represent a USB or similar port soldered to the board. The right side is a wireless chip, with a PCB antenna.

For anyone who is experienced with cross stitch, there is already some unique features of this pattern. Cross stitch typically deals with complete X stitches, shown as pixels in the pattern. My pattern has a bunch of partial stitches, where the X has half of it with a different color. I wanted to use partial stitches to make what looked like thin PCB traces without having everything be 90 degrees (and 90 degree angles are a big no-no in PCB design). I also have some singleton stitches that are off the standard grid for the rest of the piece (supposed to represent vias).

Next for the materials. Originally I considered metallic filament. It is shiny and sparkly, which would fit in with the PCB aesthetic. However basically everyone on the internet says that metallic embroidery filament is incredibly annoying and difficult to use, and that it should be used sparingly. Then I stumbled onto DMC étoile, which means star in french. These are standard embroidery filaments that also have a plastic sparkly thread with the cotton threads, so they give some sparkly effect without being too loud. The effect is quite difficult to see on camera, but looks very good in person. I also decided to use 28 count linen in black. (The internet also heavily recommended against using black, and it definitely made the stitching experience more difficult.)

Et voilà ! I think it came out absolutely fantastic. Also, bonus pic of the back so you can critique my stitches. The partial stitches weren't too difficult once I got the hang of it. I buried the start and end threads under as many other stitches I could for extra strength, and didn't cut/restart stitches if possible. I also experimented with different floss thread counts, but I decided on 3 instead of the standard 2. Then I washed it and applied an iron-on interface backing material to try and keep the floss from coming out.

Finally, after a few months of having my backpack in the repair shop for the zipper (long story), I had it back and could try and finish the repair. Sewing it on was surprisingly difficult, mostly because I didn't have access to the back of the work piece. I managed to get a sloppy stitch in that would at least hold it in place, and went back to add a secure whip stitch with a curved needle and double thread. But I think it came out very nice. Final picture 1, and final picture 2. The black fabric doesn't exactly match the black of the backpack, but it isn't too noticeable in person.

And now I have probably the most unique LTT backpack in existence!
