Let's see...off the top of my head....depending on how many of those baskets you have, how deep, etc. can you line with plastic and plant real ivy or some other type of mixed plants/flowers so that people can hang on their porch or in an office? Depending on how big/expensive they are, you could possible make this a secretaries special or Mother's Day special.
The trays can be used for a multitude of items. You can use them for silk arrangements. Neatly glue in your foam and leave space in between the foam and the tray so that you can fill that portion in with sheet moss and then design away.
You could something like they have on All My Children and grow grass in them. If you could get them to grow quick enough, you could use it for Easter. You know, add some bulb plants, plastic easter eggs with candy in them. You could also use the grass part and then add some fresh curly willow (so that you can manipulate it in a wreath shape, etc, and have some type of keepsake focal point with an angel, etc.
This is just off the top of my head. Still working on it!
Silks are easy peasy. Just make up different memorial silks with them. You can also just take a bunch of stems, tape them together in a makeshift hand tied bouquet and sell those for memorial day too. Like really cheap. Check them out for diamonds in the midst of crap. Look for great foliage or small blooms that you can use to create silk corsages.....
Last year, a real estate agent had contacted me about an estate sale. They begged me to come out and buy a huge bunch of Christmas stuff. I was really busy at the time so I told them I'd give them $50 bucks for the lot sight unseen. Well, I ended up with a car load of stuff. Some was crap, some was fantastic. This lady had about a dozen small wreaths that she used for her windows. What I did was make up new bows and added a few silk scraps I had. Then I put them on stands and sold them as Christmas Memorial wreaths for $9.95. I sold all but one which made up for the money I spent on the entire car load!
