First, take the cutter and punch an opening into the PET bottles. Use the scissors to half them completely.
Brush the sides with glue and apply the fabric onto it.
Shorten the piece of cloth if it’s too long for your bottle, but not too much because you want to cover the bottom as well. Apply more glue to make it stay closed shut at the cutting points and also at the bottom.
Punch a couple of holes and put the cord through them.
Use the glue gun to attach some decorative ribbon to the top side, all around the vase. Fashion the ribbon beforehand to make it look as pretty as possible. Put your flowers in and hang them in your garden. Wonderful!
