OH, I like the blender light, that would be a cool light for a home bar, or even a kitchen night light with a low watage bulb.
I like the birdfeeder one too, (my dad is huge on birdfeeders) however found the little birdies to frilly.
I think if you got the right day and time, the lights could do good on ebay, certainly think you could get what your asking for them on etsy.
I also think your items are great, I believe etsy is still fairly new or recently updated so its bound to be slow. Ebays slow so most others are going to be too.
