One of my very first designs I put into a knitting pattern for miniaturists to buy under my shop called Tom Thumb Miniatures. I have 2 other I made, in 1990’s. I will get around to someday upload it to my blog
Obviously you need to be comfortable to use small hair pin needles, ultimately I use .8 and 1mm needles and fine 1-ply wool/yarn from say fine knitting machine yarn cone
You too can reproduce this jumper, change the colors if you want
