I order Card Stock on the internet from CardBlanks.com or go to Art World in Victoria.
I use 5x7 Natural Cards & Envelopes NAT57CE
I use no flap clear sleeves B75NF 5 7/16 x 7 1/4, most artist prefer stick down flaps.
Wal-Mart for printing 4x6's, ordered over the internet.
Craft Glue Stick by Scotch, or double stick tape.
I prefer Craft Glue stick as it does not welt the photos.
I print my name on the back of the cards with template made in PS Elements.

San Josef Bay was one of my best selling cards.

The snow scene was taken at Rotary Park and the filter, Porcelain, is from Xero freeware.
Hope this answers your questions and comments Pam.
Regards,
Heather
