I recently found a retired Liv doll at a second-hand shop. One thing I love about this line is how you can change their wigs. They even come with a painted on short hairstyle so they can go without a wig. Mine came with the doll and 7 wigs for $10!
Even with all those possible looks, I wanted to see if I could make my own wigs, so I found this tutorial from My Froggy Stuff. To make it even faster and easier, I actually just tied a piece of matching yarn in the center instead of sewing it. You will want to sew it to make sure it stays together well if you are giving it to a child. After making the wig shown above, I decided to experiment by combing through the yarn to unravel the strands and create a softer, more realistic look.
This time I just used a clear elastic in the center to keep the strands together, I tried out different looks by moving the part and styling the ends. You can attach the wig with tape or a clear elastic, but it stays pretty well if you fasten it into a pony tail. Brushing out the pieces of yarn does result in some fluff coming off, so I used that as a short wig by forming it into a blob and tying it onto the doll's head with a piece of tulle. This works best with the thick yarn that is not twisted too tightly.
