Spongebob Squarepants fans who are planning a pajama party might like this free slumber party invitation to print. Just click on the image and the invite will open nice and big - then print however many copies you need for the number of folks you're inviting to your pajama party - and once printed, sit down with your guest list and fill in the blanks.
This invitation - like all my other ones - allow you to insert the time/date the sleepover will start - your address - there's space for RSVP and also what guests should bring - here is where you can add things like 'sleeping bag' or 'blanket' or 'swimming gear and towel' or 'flashlight'.
