What this one is
You know those evenings when you want to make something but you don't want a whole project hanging over you for a week? This little romper is for that. It's sized for a fashion doll or a small plush, so you're not wrestling with a big piece of fabric, just a neat little shape that comes together while you're parked on the porch with good light and nothing else on the agenda.
Your hands are mostly doing single crochet here, row after row, with a bit of counting when the decreases show up to shape the waist. You'll separate stitches for the leg openings and pick up a couple of short rows for the straps near the end. All told, with the swatch and the finishing, you're looking at a few hours, not an all-day sit.
