[aussie-london.livejournal.com]

Hi all!
I'm indending to make Wy's giant brush by my own but I've no idea about the sorts of material I needa use.
Do you guys have any suggestion on this? eg. should I use PVC or wood for the brush handle? etc.
I really need your help!
Great thanks to all of you! :')
