Step 3: Sewing the Planter
The bottoms and raw edges of each section need to be sewn so that when it is filled up, everything stays put.
Don't be afraid to sew weak areas a few times over in high stress areas of the fabric to make sure that they are strong enough to keep in all of the soil. I strongly recommend using fishing line for thread as it holds up well against the elements.
When sewing everything into the correct shape, it is important to fold in the edges especially where the fabric is fraying. This will prevent the rips and tears from getting larger because it will lower the stress the area receives. So the key here is reenforce and stitch into place.
For this demonstration, a thick thread was chosen and sewn in using a simple stitch. Feel free to use more decorative or elaborate stitching. Anything works as long as it holds the clothing together.
