Yes I save them the way my Dad did. Squeeze out onto a paper towel. Spread if you can. Let dry on a windowsill. Write the variety on the towel. fold up and put in a small envelope and seal. I keep them through the winter in our attached garage (lower Michigan). for planting, just tear off bits of the towel - single ply - and plant with the paper.
That is ingenious!
Thank you very much. I figured there was no way I could wash them and not damage or lose them, laf. I am definitely going to use this method. Many thanks.
