If you have a sewing machine, you can whip this up in no time at all.
First you need 6 squares of fabric, all the same size. Then they need to be sewn together like this.
Finish off the blocks, by sewing them into cubes, flipping it right side out and stuffing it. Sew the last opening together. If you hand stitch as horribly as I, you can hide it with yarn outlines.
If you have time, and the know how, you can stitch in your own pattern. Here is my butterfly.
I didn't have a hoop, so husband made me one out of a peanut can container. I do so adore him.
And the finished project should look some what like this (if not better)
I still have several more to finish up. But I think the two new babies in our family will eventually enjoy them.
