Yes! Part of the beauty of this very easy crochet pumpkin pattern is that you can substitute any stitch you'd like to crochet your rectangle. As with all amigurumi, you want to choose a tighter, closed stitch so that the fiber fill doesn't show through gaps between the stitches. Herringbone double crochet, the basketweave stitch or Tunisian simple stitch (Tss) would all make great options.
