wedding program paper/inserts

ok..i am making my own programs for the church. i typed/printed it out on the vellum..looks FAB! now i just need an insert to put in between the 2 sheets of vellum (i sheet is the front & back, the other is the middle of the program). then im gonna tie them all together with ribbon so the 'booklet' stays together. i'm having problems finding inserts that have a background picture of flowers or something nice...i keep finding program paper with words, bold pics, etc on the front. i just want a nice backgroun picture to show through the vellum a little on the cover but not overpower/block out the printing on the vellum. any suggestions/websites/anything???? i've been doing searches for about an hour & have some up with 1 or 2 'ok' ones but nothing im crazy about. any help PLLLEEAASSSEEE??!?!?!

TIA!!!
