You could also leave out the base and rather hang up your pots with a plastic grocery bag rope

How to make yourself a plastic rope
what you will need
-
Plastic grocery bags
-
Scissors

What to do:
Cut the plastic bags into strips (whichever size you want). Just remember: the thinner the strips, the thinner the rope will be
Keep the width of the strips in a uniform size. Variations in thickness will make your tote pattern look bad and be weaker at some sections
-
Group the strips into 3’s, and tie a knot at the top of each group
-
Now start plaiting them by taking one strip on the side and bringing it to the middle, then doing the same with the other side. Continue until the end
-
Once you have reached the desired length, you can make a knot again at the end. Push the knots through each side of the holes in the pot
