Here is another quick and easy DIY, that is also very inexpensive. I purchased 5 glass jars from my local dollar store, that ranged in price from $1.50 for the smallest to $10.00 for the largest.
I went to Michael's and selected Martha Stewart Craft Paint in varying shades of grey, but you could use any colours that you wanted. The nice thing about this paint is that after 21 days the paint is cured and can be put in the dishwasher. The blue shades are for another project :)
It took quite a few coats before they were opaque, but I am really happy with how they turned out. I think they look much more expensive then they are. You could get really creative with patterns, and colours.
