Step 1: Wait until your mom has spent no less than 3 hours cleaning the house
Step 2: Go to the linen closet and remove everything that looks sheet-like by pulling neatly folded stacks from each shelf onto the floor. Don’t miss great grandma’s white tablecloths.
Step 3: If you’ve pulled down a fitted sheet, wad it back up and shove it on the floor of the linen closet. Fitted sheets are NOT blanket fort building material.
Step 4: Build fort. Stacks of books make great sheet anchors, so feel free to remove all the books from the bookshelves.
Step 5: Play in the fort for 5 minutes to 3 hours. Make sure to end blanket fort play-time by getting into a huge fight with your brothers.
Step 6: Whatever you do, do not clean up the blanket fort.
Step 7: When your mom insists, wad sheets, tablecloths and anything else you’ve used and shove it into the linen closet. Close door as far as it will go. You’re done.
