@toribug11 Thank you so much ❤️ ❤️ ❤️ I'm really happy with how it turned out. It took ages, almost 2 weeks, because I have kids and got to work on it only in the evening basically. I absolutely COULD NOT find enough black floss where I live, nor on Amazon even, so I used yarn of a similar thickness, which resulted in a slightly warped product, but washing and reshaping, as well as gluing some felt on the back helped with that.
Your measurements are very close! Mine ended up being 3 1/4 x 13 3/4. The slightly smaller dimensions may be due to the less dense nature of the yarn, ie. it squishes together a lot more easily than regular floss.
Super fun pattern to do, very well done on your part 😄
