The dahlia top pattern is a size inclusive and made to measure pattern. This means you take your own measurements and then follow the instructions, this makes it customisable for any age and size.
The pattern is written in English only using US terminology. It is a beginner friendly pattern which detailed steps and photos throughout.
You will need any type of 8ply (DK) weight cotton and a 3.5mm crochet hook. You can use any other fibers if prefer. I used roughly 450m for the size small UK 8.
