Kids love making forts and tents. The simplest one would be a blanket or sheet thrown over a table. However if you still want to be able to use the table, this instructible will show you a simple way to create a tent for your child that reduces the risk of everything on top of the table being pulled off.
Step 1: Materials
For this tent you will need:
Fabric, old sheets, remnants, or scraps
Buttons (doesn't matter if they match)
Bias tape (at least 4 yards, more if your table is large)
Sewing machine or hand sewing needle and patience
1/4 inch elastic
A child who wants to play in a tent (Or hey I guess this could be for adults as well. I'm not going to judge.)
Basically, this table tent is only a step up from throwing a sheet over the kitchen table. It isn't hard to make but it will use up some scraps or remnants, and it will let you use the table for drawing or eating or what have you without taking the tent down. You could make this as complex as you like, with windows and pockets and doors in every side, or just as simple as four featureless sides. I made each wall different.
