I make most of the little one's summer clothes. However, when I can buy new t-shirts at children's place or walmart for $2, Id on't worry about tops.
I make mostly loose capris from cotton. I often find it at yardsales..lol. So really cheap. A 2 yo shorts would use 1/4 to 1/2 yard. Capris I can do 2 to 3 pair in a yard..lol. Be creative, add little details, ruffles, bows, sew on extra buttons to make a design.
Skirts are very simple. Measure the childs waist. Multiply by 1/5 to 2. Measure the length add 2" to the top and 1/2" to the bottom for elastic casing and hem. Stitch ends together. Make casing and hem. Very quick. You can use 2 pieces but if you make it full enough no one sees the seam anyway.
Making shirred tops is easy too. Measure chest. Double. Hem top and bottom. Draw one straight line. Use that as a guide when sewing. Wind your bobbin with elastic thread. Then just stitch that line. Do the next line, starting at the same side. Keep doing it until you're where you want to stop. Stitch side seam or mid back. Use iron and steam it to get it to shrink up. Add basic straps to the top. There a cute haltertop. Use a longer length, shor only to the high waist and make a sundress, simple cute and comfy
