Caged Halter Top
This is the kind of make that looks far more complicated than it actually is. Brittany Jackson, the maker behind Made by BJax, builds the top from two shaped cups joined by an airy chain space netting, then finishes it with a pretty scalloped fan edge. The caged sides and back lace up like a corset, so you get an adjustable, dressed up fit without any tricky shaping.
It works up in lightweight cotton and is sized from a small on up, with the chain and row counts for each size shown right in the video. Brittany nearly finished a whole top from a single skein, so it's a satisfying low yarn project. Many makers finish it across an afternoon or two.
