Getting cheaper cribs is just one way to copy the twin boys nursery for a cheap price with similar results. You would save a couple thousand dollars by getting less expensive cribs, but you would also save a bundle by picking up a pair of used bed crowns.
I don't think that I found the exact ones in the picture on the website, but similar ones were on sale for over $600 each!
And you can buy a used set online for that amount or less if you're willing to buy some made of that lightweight plastic stuff and paint it gold and then antique them to make them look like painted wood.
I also found antique white and baby blue stripe fabric similar to the fabric in the pictures of the twin boys nursery that you could buy at a very cheap price...the problem is that to make the crib canopy AND those ruffled crib skirts you would need a lot of yards of fabric and it's hard to find fabric on sale at a discount when you need that much. Just my two cents on how to copy that twin boys nursery for a cheap price.
