If you know how to make a simple granny square, you’ll be able to make this crop top. It’s made with just two granny squares, and two half-squares (triangles). There is a lot of different options for this pattern. If you don’t want your top to be see-trough, just make a basic solid granny square for the front. The pattern is written for the size Medium, but it’s easily adjustable for many other sizes.
(Not recommended for bra sizes larger than DD!)

What you need:

-Crochet hook 3mm US C(tight) or D(lose)
-Fingering weight (Super Fine) cotton yarn – around 500m or 550 yards for size medium
Optional: tapestry needle – if you prefer to sew the pieces together
Optional: measuring tape – you don’t need it if you can try it on as you go
Note: You can use any yarn weight, just make sure to use appropriate hook size.

This pattern uses US terminology.
