Picked up a bunch of 3/8" diameter by 3 1/2" long glass test tube type inserts at the last WWing show and finally got around to using some of them. Weed pots are nice but won't hold water. Make 'em a little bigger and add the inserts and they'll actually keep a flower alive for days.
So if you're looking for ideas for stocking stuffers or small presents - have a look.
