I’ve been working on this for a while (since around the start of November?) i’ve been working hard to get the textures working, but i wasn’t able to upload it to Garrysmod.org until Christmas day when i got it all fixed up and working, but better late than never, right?
I’ve yet to see any Christmas stockings on Garrysmod.org and i haven’t bothered to go looking around Facepunch for one, so am i really the first person to make a Christmas stocking despite Garry’s Mod being around for many Christmases? That’s pretty neat
Anyway, i apologize for not posting this topic after i’ve uploaded it on Garrysmod.org, i’ve been forgetting to do so, so here it is, and enjoy!

Change log:
Removed some unneeded triangles from inside the bottom part of the stocking
Slight texture fixing with the inside of the white cotton part
Fixed collision mesh to fit the model better
The model looks nice.
