Last weekend I took my daughter on a train ride at the Zig Zag Railway near Lithgow in Aus. They did the whole Harry Potter thing and turned their train into the Wizards Express and everybody dressed up like witches and wizards and such. I went as Professor McGonagall and here is my hat that I made.
I think I did well considering I don't really sew. I also made robes for my daughter and I, but I havn't got pics of them yet.
The hat is black, I can't quite get the light right with my camera.
I used crushed velvet and cushion stuffing.
You cut 2 donut shapes, sew them together on the outside, turn inside out and lightly stuff with cushion filling (too much and its too heavy and just flops) then make a ring the same size as the outer part of the circle out of piano wire and stuff that in there too, it helps hold the shape. Then sew the inside circles together.
To make the cone cut 3 triangles, curved on the bottom. 2 from crushed velvet and 1 from a stiffer material, I used thick felt. put the 2 crushed pieces together with the outside faces touching each other and then put felt on top and sew down both sides. Turn inside out and sew the bottom.
Pin the bottom of the triangle to the inner ring of the donut and carefully sew (sounds awkward with the wire and all but if I can do it anybody can).
Then sew the triangle into a cone. I did that bit by hand so that you couldn't really see a seam from the inside (just me being fussy)
Add some ribbon and a fancy brooch and a couple of feathers and there you go.
I hope thats not too confusing to follow. If you have any questions just ask me.
