and I had a really tough time making Miku's megaphone for our Love is War cosplay, so I made a tutorial to help out anyone else who wants to make one. We tried several different methods but this is the one that ended up working out well.
____________________________________________FAQ:Where did you buy your megaphone?
I bought my megaphone from a Taobao agent (someone who speaks English and will order items that you want from Taobao, which is basically the Chinese version of eBay.) You give them the URL of the item you want (along with shipping address, email, etc.) and they'll order it for you. However, that still leaves you the task of finding the right item yourself on Taobao, which is entirely in Chinese. Luckily I had Google Translate and a friend to help me out with searching** (megaphones are more commonly called 'speakers', I believe.) I ended up ordering this megaphone: [link]
Since it was from China, after currency conversions, it was roughly $5 USD, but the shipping and the agent fees it ended up around $45 total. The English website to order from Taobao I used is here: [link]
**If you want to search for a LIW megaphone (already painted) on taobao, search for "恋爱战争 喇叭", if you want to find just the megaphone and make it yourself, search "喇叭".
