Makin' Valentine's Cards

Last week I got away to a Card Making Workshop.  I found it through Meetup.com.  One of the other moms on one of the meetup groups I belong to recently became a rep for Stampin' Up, which is a high quality stamp company.  It was a lot of fun!
Meetup.com for those who haven't heard of it is a site you can join all across the world.  Each city has people who host groups looking for like minded people to meetup.  The range of groups is incredible.  I've met some great moms that way.
Onto the cards.  This was my first go at card making in a long time.  I'd made our wedding invitations, but they were very simple.  As well I made birth announcements for our first born 6 and half years ago.  I used to do a lot of scrapbooking, but since kids the scrapbooking has fallen by the wayside.  I will get back to it one day.
The cards were fun once I got into it.  Our host had a lot of product to choose from to use and a lot of samples to inspire.  Here's what I came up with.

I've just cut out the quilt top for my first non-quilting kit quilt.  The only part I haven't done is cut out the rectangles for the border.  The directions need 40 3 1/4 by 5 1/2 squares.  I just don't know what material to use.  I have a yellow, but I don't know if it should be all yellow?  I still have enough of the other fabrics left to cut out some with those.  What do you think?
