I was totally confused at that part too! I think it's four separate pieces, because she says in step 14 to sew the fronts together. Since it's plural I assume she means two? So I think it means two back pieces and two front pieces! Hope that helps!
I guess it isn't all to hard. But I do have a few questions. Are the horns necessary? My family doesn't know I'm a Homestuck (or about most of my fandoms, for that matter), and I'm not in a hurry to tell them why I have horns on the hat I'm making. I suppose I want to make the hat for a subtle reference and to feel closer to the fandom rather than cosplay. Also, what do you mean by step four? Is it measuring for the curved part?
Uhhh... I can copy/paste? The measuring is kind of tricky I suppose. Basically, take the head measurement, divide by 4 then mark that line on the paper as a horizontal line. Then measure the distance from the top of your head, to your eyebrows. That will be the distance from the top of the cone shaped piece to the horizontal line. Make sure it's centered. Then the measurement from the top of your head to your hair line would be the distance from the top of the cone measurement, mark that line the same distance as the 4th of the head measurement. Then make a curve from the bottom line the the left side of the hairline line. Then slightly curve that line to the top of the cone mark. do the same for the back. Then for the other piece, you just do the 4th measurement with the top of the cone like you did before, then don't add the hairline measurement. You'll simply curve the front and the back the same. I can't explain it any further than that. >_< Sorry, I'm bad at explaining. ;~;
I found furry tutorials really helped me make the tail, and the paw feet! This tutorial is similar to what I used for the feet. www.youtube.com/watch?v=PowYGG… I don't have any pictures of my feet... ;~; But this is the same method I used if you are interested in that. Here's a good tutorial for the tail www.youtube.com/watch?v=6suvoM…
No, you can sew it by hand. It just takes longer. Do all of the steps, but just hand sew to the pins/notches for the horns. I'd recommend using a backstitch, since it has a less chance of unraveling or breaking.
