I have about 10 vases such as this. Do you have any rooted bannana cuttings or lobelia. I am also not a picky trader. Let me know what you have, I would like to help.

try the local hospital and nursing homes- they keep some, but throw a lot of these away

When I needed a large amount of bottles i went to the redemption center ( in Iowa we get paid to recycle, not sure if this is the case in your state) They sold them to me for the dime that they would get and there were lots to choose from. I run a children's garden in Belmond and would love to know how you make these feeders and any other ideas for children's projects. good luck with the project!!

Try thrift stores. You can get them around .50. Maybe lower. They usually have a ton and all different kinds.
