Little Turtle Knits Undersoaker
Boy or girl, this pattern will have you covered! With underwear-style front loading legs and a variety of leg cuff options (including rolled edge as shown above, hemmed, ribbed and picot) as well as a fully enclosed elastic waist for easy on and off (no fussing with drawstrings!)
This pattern has detailed, in-depth instructions for a skirt with delicate (but easy-to-knit!) lace edge and attached undersoaker to cover diapers, and also for the undersoak on it’s own.
