dress, apparently its easy to sew: Its just 4 rectangles. Measure shoulder to hem length, then girth at widest part (hips?) and divide by 4. Add seam allowance. Sew allowing for neckline, arm holes. No pattern needed. 1/2 hour, max!
Bed in a Bag: fold a twin sheet in half long ways and sew ends together, next sew in five equal sections the size of a pillow case, next insert pillows leaving ends open to remove pillows and wash cover.
