The cumulonimbus mittens are so named because the fluffy sproingy tonal grey yarn my sister dyed and handspun reminded me of stormy clouds. The lace in the pattern provides a little ventilation. The cables were inspired by cumulonimbus clouds which seem to grow vertically in columns.
Finished size: 9"/23 cm circumference, 10"/25.5 cm length including cuff to fit an adult. Size could be altered by altering the gauge.
Designer used: 2-ply handspun yarn spun from 80% superwash merino/20% nylon roving that was dyed with black beans and had a wpi of 10-11.
