My almost-5 year old nephew wanted Rainbow gloves, then “dark Rainbow” gloves which he specified as having black, dark brown, dark red etc…so voila!

The pattern will give you child size gloves as follows –

5.5″ wrist
8″ around hand
6″ long (2.5″ cuff)
but it is easy to adapt to any size.

The wrist ribbing is made from rows of sc in the back loops. You can make this as long as you want. The hand part is made from rows of regular hdc. Once you have the length you want you keep making rows until as wide as you want and then follow the pattern for the closing tab and button hole.
