Not actually top today but some blending fibre.
This is totally cool, glow in the dark spinning fibre. I've seen some glow in the dark yarns for sale but this is the first time I've seen fibre. Not that I've been looking though, I'm sure it's been around for ages. This lot is from zauberzeug on Etsy.
I haven't been able to find many projects with it but someone used it to make an owl soft toy which seems more than appropriate.
