Pottery is one thing I have collected for over 10 years or so. I go through phases on other things I collect but anytime I go junking/antiquing I always look for vases, planters, flowerpots etc. I am just going to post a few photos of my pottery collection. I collect mostly McCoy but I also have Shawnee and Weller items. I usually look for the color (pastel colors most of the time) but design is also a factor. Even if it's a color I love but the design is just something that won't fit in with the rest of my collection I will pass on it.
In the photo above, the aqua vase is the very first piece I ever bought. It quickly grew from there!
