I'm more into knitting than sewing but I admire the effort and creativity cosplayers (and their costume designers) put into their hobby. I love to play tabletop-RPGs and put a lot of work into my chars there even if they only exist in my head or as stats on paper ;)
If you like to take a look at our #needleworkmonday community and join us next monday and show us some of your sewing in a post.
