So I would like to design my own slim line birth announcements using photoshop, but my customer also needs to be able to have the envelopes to go with it. Is it possible to design my own, upload it and have envelopes to go with it? I didn't see that option at checkout...all I saw was the premade birth announcements that I put my picture into that comes with the envelopes. Thanks!

Here is the link to the page that you are looking for.  Hope this helps!

You can upload your own, and then they send the envelopes with the printed cards.

Mpix does a GREAT job with them. I designed my own and Mpix printed front and back 5x7 with envelopes for about $19.00 for 24. I think I'm right on the price

I uploaded it on a Monday and we had them by Friday and we are in FL.

I am working on an announcement right now.

Oh fabulous!! Thanks so much...I'll check the link now ;-)
