Just wanted to share where I bought my keycard holder supplies!
Coil bracelet keychains ($.15 each or $1.80 per dozen)
Badge holders on ebay ($.20 each or $.99 for 5)
I'm going to use a business card template in word to create the insert! Hope this helps some of you! I figure I can make 25 key card holders for a grand total of $23 including shipping!
