I am surprised and proud to tell you that last week, I built something! I did a little IKEA hack and turned our KALLAX storage unit into more of a wine rack. I love the way it turned out.
Rob was nice enough to help me out (it did involve a little bit of math, which is always scary for me) and now we look like we really know what we're doing when it comes to wine storage. And all you need is a couple pieces of plywood!
For this tutorial, I used wood glue, because I'm not a professional and when it comes to DIYs that involve lumber, I usually try to find the easiest way to make it happen. The wood is light enough that the glue is sturdy (plus you're putting it in a cubby afterward, so the whole thing gets supported by the shelf). It's all very technical.
