Wigs x2£29.68Bought


Wig(s) vs hat (Posted 24th April 2013)

Tried out Marcie's hair again today, this time with the hat. It can sometimes look a little strange, since the hat doesn't have much give to it at all, and I'm forcing a huge amount of hair under it (2 wigs! Marcie, why?!), but I'm happy with the overall outcome.

I'm going to be a hair monster! If anyone wants to come and join the hair-brushing sessions we're going to be having all day to keep this beast tamed, then feel free! xD

Onwards to actual sewing (Posted 20th February 2013)

I have everything bought for Marceline now, just waiting for the 2 wigs to come so I can make her hair. The only other bit of sewing I have left to do is adding the ribbons to the back of her boots, which I'll probably leave closer to the time, just so I don't end up overworking myself with uni things alongside cosplay. Looking forward to getting everything done now, because at my current pace I should have loads of time left to start working on some of this summer's cosplays a little earlier than I thought! :D

Progress (Posted 26th November 2012)

Did a trial today of what I currently have for Marceline, and it looks a little better than I thought 8D I still need to make adjustments to some stuff, like the trousers because they're a little big, but on the whole there's not much to do.

I need to buy a new vest at some point, because a) I'd like one with a better fit, b) this one's not quite red enough, and c) it's not my vest xD

Possibly going to buy ribbon for the hat today, and I might sew that on later just to feel like I've actually made progress. Also going to buy boots and gloves today, so hopefully they'll arrive before Christmas and I can start work on those too :)
