Working on this webpage brought back a lot of memories for me. I did the Color unit with Natalie 5 years ago, right after Rebecca was born. (Those of you who have known me for the past five years through my curriculum writing, know that I wrote the Families unit to do with Natalie because I was pregnant with a new baby at the time.) Then, once the weather warmed up a bit, we moved on to a new topic. I picked planting a dye garden as the Nature topic for the Color unit because it fit so well with the idea of learning about Color and because I was interested in learning how to make natural dyes. I designed the Seeds for Your Dye Garden page because I myself was shopping for those seeds and wanted a list of vendors which carried them. I hope it's helpful to others who are now looking for that sort of thing, whether you have a preschool child or not!
There are now updated live links to vendors for all the dye plants listed in Rita Buchanan's excellent book A Dyer's Garden: From Plant to Pot: Growing Dyes for Natural Fibersand a link to an Excel spreadsheet which I created to keep all my information organized (which plants I ordered, when I started them, whether I like them and would buy them again, etc.)
