Alright, so this one isn't really upholstery fabric but (back when I could remember how to make Photoshop do my bidding) I thought it'd be a fun challenge to create a couch based on a certain TOS costume:
Obviously this sort of sidesteps the conceit of these posts as it definitely does not resemble conventional upholstery fabric but I figure couches can dress up for Halloween too! This sofa's material was taken from a rather infamous episode of The Original Series. Its cushions were taken from a second character within the same episode.
Hint: Technically there wasn't enough of the silver for me to work with (the costume was rather skimpy) so I had to make my own.
Guess whose couch this is in the comments! I'll let you know the correct answer on Halloween!
