Save small yogurt containers and water bottles

We are hoping that we will have enough seedlings for each of our members to take home three plants of your choice in your first share.  But we need your help with the containers.  We have about 400 small pots and need about 600 more.  Rather than purchase them, we would like to re-use your small plastic containers.   A single-serving, 6-ounce yogurt cup or an 8-ounce water bottle cut in half, are about the size we're looking for.  We would like to collect them at the Spring Festival (May 4th), so we can have them filled and ready for the first share.  Thanks for your help!

Your farmer,
Carrie
