I came across this idea on Pinterest about a month before Christmas. It's so simple! I knew it would be perfect for our kids- who are SUPER into legos, so I picked up the end table from IKEA for $8 and ordered the Lego base squares from Amazon. They were about $6/each. Then I picked up a bottle of Gorilla glue at Target and assembled it. On Christmas morning, my husband had a whole castle set up on the table when the kids came down stairs to see it. I doubt a single day has gone by that the kids haven't used the table.
