I dunno how you can finish 8 costumes in 3 days, Elin, but I wish you the best of luck. Even on a good run, it takes me 3-4 days to finish the simplest of costumes, mostly because of work and school.
I have finished what I'm going to be able to finish for A-Kon. I dislike the fit of my Erza costume, mostly because I didn't have proper time to use slopers and fit it to my own body proportions, but I'm just going to have to make it work for this year. I still need to trace the Fairy Tail mark onto vinyl and purchase tights, but that's easily enough done.
Today is for laundry and general apartment cleaning (as well as destressing), and tomorrow will be packing and cosplay pics.
