This tutorial for a crocheted yoke was made in collaboration with La Tessoria!
Sizes:
Tutorial is written for two sizes, but it is extremely easy to make it in any other size. All you need to do is to make as many squares as needed to make it fit around child’s chest. Then cut the fabric according to your own measurements “desired length and width of the skirt part.”
Baby (9-12months)
Toddler (up to 3 years)

Materials:
any sport weight yarn, approx. 50g for smaller size and up to 100g for bigger sizes (I used a linen/ viscose blend yarn, but any other yarn will work just fine. With the yarn weight you can also make experiments and use some thicker yarn as well. In this case you will simply have to make less squares.

4 small buttons (can use only 2 if prefer)
