Paint the saucers with a good quality outdoor paint in the color of your choice. Paint all sides including the bottom. This may take more than one coat. Be sure to dry in between coats as well as dry completely before use.
While those are drying, you can start decorating plant pots with fabric. Make a small mark on your pot and start on one end on the back of your fabric. Roll your pot as you trace a line on the top and bottom of the pot leaving about 1 to 1 1/2 inches on both sides. Continue until the mark you made on your pot is all the way on the other side.
Then use scissors to cut out your piece of fabric. It should look something like the below image. Place the fabric on wax paper.
Shake your Mod Podge Ultra well (for around 10 to 15 seconds). Then spray the piece of fabric completely.
Wrap the fabric around your pot and trim any excess with scissors. Be sure to leave enough to fold over the exposed edge so you are left with a finished looking seam.
Then wrap the excess around the bottom of the pot. Make sure any holes in the bottom of your fabric plant pots are left open for drainage. You can also wrap the excess around the top edge.
Then spray the entire thing with a coat of the Mod Podge Ultra until the fabric has been completely covered. Continue to work your fabric until it is smooth. Set on some clean wax paper to dry. You will need to allow your DIY fabric plant pots to dry overnight. You will need to clean out the pump on your Mod Podge Ultra once your project is complete. I unscrew the pump from the bottle and run some water through it before storing to prevent clogs.
