I was very excited to find Dr. Who fabric. I know the many fans of the show will be excited to have their own project bag representing their favorite show as well. This bag represents the show "Vincent and the Doctor" from 2010. The exterior in both bags is 100% cotton, the interior of one is 100% cotton the second one is made from a recycled fabric. They have a ribbon drawstring and a toggle to secure your project inside. This bag is excellent for small projects such as amigurumi, socks, maybe a small t-shirt. The bottom is 6.5 inches square and it is 9 inches tall.
