I used a Cindwood Universal sock loom with 3 wedges that have 2 pegs on the wedge in the 1/4” gauge loom. Universal hat loom in same gauge could be used.
There is a full video tutorial on the mini version. A newborn version is different but no video tutorial. Minor changes.
The mini baby can be bought at Wal-Mart in the childrens section.
I used the china brand of bamboo cotton yarn you can get on ebay, it doesn’t even use but about half a skein. It is a fingering weight.
This is an advanced pattern as it uses kitchener cast on, short row heels, wedge increases, wedge decreases, short rowing. This garment is all in one piece with only 2 seams.
