The Mira top is a made to measure and size inclusive design, this means you take your own measurements as directed in the pattern and then follow the steps. This means it can be made for any size and age.
The top pattern is written in English only using US terminology.
The pattern is an advanced beginner level, however some beginners may find it okay as there is plenty of photos throughout each step to guide you.
The crochet top pattern uses roughly 1200m of 8ply (light worsted or DK) weight yarn, I used wool but you can use any fibre. I recommend cotton which has a nice structure and soft feel. Use wool or warm fibres if its a winter wear.
