|Lego themed fabrics from Spoonflower|
Spoonflower to the rescue! I found some awesome Lego-themed fabrics available to make him reversible bags to purchase even more Lego gear from the Lego store (who all rave about his other reversible bags).
The fabric arrived 3 days before his birthday, so I had to do some stealthy sewing before he came home from work or woke up in the morning. I would look up every time a car went by, or heard anything stir--and always ready to make a mad dash to tuck everything out of sight before he ruin his birthday surprise. Fortunately, I didn't have to resort to any drastic measures, but it was close.
