XD I just bought this DVD days ago! I loved it! <33333
Oh, what a great idea! So you'd like to do a Black-Feathered Howl? Oiee, I suggest, rather than gluing feathers/feather equivalents, to your arms, that you find a full body suit, the kind that has long sleeves up to your wrists and down to your ankles, and glue feathers/whatevers, on. Hotglue seemed to make feathers hold great on this feather fan I made once. Make separate wings that run up to your shoulders and have a little bar on the inside where you can grip and keep the wing on maybe.
And for your second question, yes, I think one without no sewing knowledge could pull one off. Perhaps a pattern to help you out to see the pieces, or a visit to a thrift shop to buy a peasant-like shirt, regardless of color, and take it apart by the seams. Use those pieces as a pattern on the fabric of your choice.
^^ Maybe you could do the Howl where he has orange hair, nothing but a towel around him. Some green tinge to the skin would be awesome!
Haha, best of luck!
So sorry for my absence, I'm in the process of moving! Akamaru ready for take off!
