"I use this randomly during the school year for certain events but it really is a bigger part of my summer music camp program. The kids love being able to sign their name, date, pictures, comments on how much fun camp is.....It's a great advertisement for my summer camp too. I drape it over the registration table so the families can see one of the activities that will be featured. I've used this for grades K-12 with classes as large as 28 kindergartners or 18 teens. They all love it. My only suggestions are 1. to use non-puffy style fabric markers (because the puffy paint will dry, crack and eventually begin to chip and fly off after usage) and 2. to encourage the kids to NOT use the handles and hold on to the edges of the parachute instead (because in their excitement the kids tear the handles which eventually rips the fabric). I have never been brave enough to wash this parachute so I don't know how the fabric lasts in the wash or how badly the marker ink may or may not bleed into the fabric. I've had my parachute for 4 years now and I plan to replace it this year due to wear and tear."
