I made a rainbow wig for one of my dolls and got a lot of interest in how I made it, so here's a little tutorial! I threw another one together today with the leftover materials from the first one :)
I don't specify how I made the wefts in the tutorial, but it's basically the same way as this, the only difference is that I sew them onto tracing paper and tear them off instead of tulle.
I used some cheap braiding hair because I needed six different colors, but only a little bit of each color, so I wanted to save some money. You can buy it for $3.55 a pack at Doctored Locks, they have a low price guarantee and a huge selection of colors, so I like buying from them :) Or if you have some more money to burn feel free to buy wefts pre made somewhere like Cool Cat, they have a huge selection of doll hair wefts. If you're looking to just make a junky practice wig I recommend buying a cheap weave from a beauty supply store in your area, they come as cheap as $8 in my experience, and are good if you don't want to waste money on more expensive hair just for practice!
On to the tutorial!

-Stretchy, thin fabric for the wig cap

See the rest after the cut!
