The Thalia top is a made to measure and size inclusive design, this means you take your own measurements first and then follow the instructions. This makes it completely customizable and can be made for any size and age.
The instructions are in English only using US terminology. The level is advanced beginner, however the patterns contains detailed steps and photos throughout.
I used DK weight cotton yarn for this top, however it can also be made using fingering or sport weight cotton too. I used roughly 800m for the size small (UK 8).
