This pattern is made in such a way that can easily be made to custom fit. It is using 2 pieces that make this bolero.
The amount of yarn will vary on your size, if you are petite it will only take a single skein of Peaches and Cream, if you are plus size buy 2, it will use a little of the second skein.
I used the CinDwood 29 peg 1/2 gauge loom to complete this pattern, but the pattern is written for a 24 peg loom as well.
