Why not get iron on transfers for color printers, find the pics of buds you want to rest your head on and make your own? I know you get about 10 iron on sheets 8.5 x 11.5 for about $10 at most places that sell printing supplies. The color printers are under $30 brand new, and invest in some good sheets that will last a for years (400+ thread count). The whole project could be done in a few hours exactly the way you want it for under a $100.

Look on ebay they sell what your looking for" pillow case pot leaf " is the search I used and $25 for just the pillow case someone is probably making themselves the way I just explained.
