I was thinking about making grow bags, in a fast and inexpensive way.
I have black garden fabric from Costco, it is 48" wide.
Step 1. Cut a square 48x48"
Step 2. Cut in half.
Step 3. Sew the rim on long side.
Step 4. Sew side and bottom.
Grow bag in process.
I called them "ears". Fold the bag.
Make the folds and sew them.
Step 6. Turn the bag inside out
14x14x14 inches or about 12 gallons.
It took me 30 minutes to sew 6 bags
