I need design on how to store / hide adjectives of my christmas presents from the kids now that they're for a time older... especially two really colossal ones I got. A pool table and a colossal HCTV.

I really want them to be a surprise and we don't have much space.

I can't store them under my bed since I hold a platform with no space underneath. They could find them surrounded by the garage. They're too heavy for the attic. I don't enjoy friends/relatives close by to ask.
Shades at Starbucks...anyone?
Answers:    my parents always kept our presents within the trunk of the car, but I'm guessing that wont work beside those two presents. You could always ask a neighbor or one of your kids' friends parents. We kept some presents at our house final year for someone DH worked with.

set up transfer for the day in the past Christmas, so you can enjoy them on Christmas sunshine.
