There are a number of different vendors that sell sand; one particular one I found had over 60 colors, including "sparkle" sand....ooooohh...right up my alley! Although, you can also find some basic colors at Hobby Lobby, Michael's and JoAnn's.
I'm sure through thrift stores or garage sales I may have been able to find a decanter that I liked, but I had been admiring a number of styles that Hobby Lobby carries. So being the frugal gal that I am I used my 40% off Sunday coupon to buy one I really liked.
I chose to use four different colors of sand and then just began pouring and tilting the decanter to get the effect that I wanted.
This project could make fun Christmas gifts, housewarming, bridal shower....you just need to know the home decor colors, get your supplies and you're good to go!
This literally took me about 20 minutes to put together. That included taking the pictures.
