You are purchasing a pattern and not an actual diaper. This pattern makes a "OS" Petite Fitted Diaper with a fold down rise or snap down rise for adjustment. Diapers made using this pattern are generally made from knit fabric. Make your fitted a hybrid by using anti-pill fleece for the hidden body layer and go coverless for longer! This pattern is a petite version of my popular OS Fitted pattern. It is designed to fit smaller babies/toddlers. This is not a true OS diaper pattern, it is more like a newborn to small medium fitting babies around 8 pounds up to 20-22 pounds depending on build. This pattern has been extensively tested on babies of all sizes in the fit range. This style of diaper requires a cover as it is not designed as a waterproof diaper. Make your diaper with snaps or leave them off to use a snappi or diaper pin for a truly custom fit! It works great as a snappiable diaper when made with a terry or other grippy knit fabric as the outer layer. Pattern includes instructions to make a basic turned and top-stitched Petite diaper. This pattern can be sewn up exactly like the regular OS Fitted, it is just smaller :) Included with this pattern is the NEW Rocket Bottoms OS Soaker System pattern pieces. This soaker system is designed to work with all sizes of diapers. It adjusts through multiple sizes. This is the only soaker system you need!
