I tried to google it for you. �E-how suggested just drawing your own with magic marker http://www.ehow.com/how_2187720_periodic-table-pillowcase.html. �They also said you could use an iron on transfer, but I googled that and didn't see one. �This site says you can make iron on transfers from blanks using just an ink jet printer (maybe kinkos can do it for you) for $10 plus the cost of printing. �http://pubs.acs.org/doi/abs/10.1021/ed082p517
