A lot of kids love to play with LEGOs. If yours are among them then you probably have a quite large collection of these little blocks. They usually create quite a mess so you probably want to organize them in one place. DIY Lego play table could become perfect solution for you.
To make such table you need a simple and cheap side table and some Lego base plates. Measure and cut these tables to cover the surface of the table. Spray their backsides with a permanent spray adhesive and apply them to the tabletop. Wait a bit for adhesive to dry and show the table to your kids.
