he mariposa top is a made to measure size inclusive pattern, it can be made for all sizes but you need to take your own measurements, which the pattern walks you through. You will need any 4ply (fingering) weight cotton yarn and a 3.5mm crochet hook to match the pattern gauge, I used roughly 725m of yarn for the size small (UK 8). This pattern is an intermediate skill level, although I believe it will also be suitable for advanced beginners as I have added detailed steps and pictures throughout each stage.
