Sample - Quilted applique and free machining

Looking at my research into human cells i decided to create something similar using stitch, the cell i was looking at was the bacterial cells called Staphylococcus aureus.

 By pinching the material on the reverse side and using a simple stitch to sew the material together i created the oval shapes. Once i had turned the material over i realized you could see the stitch and i didn't like it as it looks messy. I then remembered a technique i looked at a few years ago which was quilted applique and thought i could use this technique to create the ovals. After i had successfully attached and stuffed the fabric on i then used the free machine to sew on the lines about the ovals to make the sample look more like the image from my research. Here is the out come.

 I love how it has turned out and also i have left on the loose ends of the threads as they also add to the sample. The reverse side also looks good although by my picture you can not see as good.
