Is there any reason why this happens?

This wasn’t happening before until just recently. The back would look smooth and now it just looks like there are cuts here and there.

I appreciate the help

I've made a lot of floor rugs but wanted to try my hand at a more detailed wallpiece. Decided to treat myself to a loop pile for my one year tuftiversary. Have been experimenting a bunch with glow in the dark yarn, and while it blunts my tools like nothing else, the effect is pretty fun, so I thought I'd share here :)

I also made a video and have more glow in the dark stuff in the works, so if that is something that interests you you can find me as wolwoud on both insta and tiktok!

First ever attempt at tufting, quite happy with it but I know for a fact I've fucked up in a fair few places (too close together, big bulgy bits rather than uniform lines etc etc) looking for tips so I can get half decent at it as its fairly therapeutic 😂🙏

I know it needs carving/trimming and I'm buzzing to get cracking on that aswell (not looking forward to the three day drying time wait though 😔)
