-Made smallest size for my smallish 4 yo using the chunky pattern instructions. They fit perfectly
-The chunky instructions are actually for worsted weight yarn, not chunky yarn which can be confusing, so check gauge on pattern before you choose yarn.
-For the M1, I used M1L for the first one and M1R for the second one which makes it slant perfectly into the thumb.
-I kitchener stitched the mitten top, instead of pulling the yarn through all the stitches.
