Wow, thanks so much! Be sure to check out clearkid's tutorial on how to make one, and my tutorial on how to decorate your Pikachu hat.
It would be extremely difficult to sew a pikachu hat by hand, but it could be possible if you are extremely thorough with your stitching and extremely accurate... my only concern is that your hat will be extremely delicate. If you've got the inspiration and the dedication, nothing will stop you!
This is my favorite pikachu hat on the internet! you are inspiring for me! i wish to make a pikachu hat, but i don't know how to cut the fleece into that shape..can you help me? if you don't have time it's okay but please and thanks!
