Finally getting around to the last missing piece of my costume!
Just finished the tailfeathers and assembled them into a full tailfan today:
There's 11 feathers total, ranging up to about 26 inches in length. According to my hawk model, this gives the correct proportion of primary feather to tailfeather lengths. They extend just past my knees, which seems to be about right.
This next week I hope to get the connections made to the wings and try everything out. Might even be done in time for FC if I get lucky. ^v^
