Hurm.. I'm not good with graphics but for the simpliest option, you can use even Paint application. For a better picture, or should I say to make it more creative... you can use Adobe Photoshop.. but then it takes time to learn how to use it though...
I LOVE MBLAQ, THEREFORE A+ IS THE FIRST FANBASE THAT I REALLY JOINED! ㅋㅋㅋㅋㅋ
Curently I'm obsessed with Miss A Suzy, Eunji APink (thanks to MBLAQ) and CNBlue!
