Knowledge is the key - 2 challenges

Hello, it's Saturday and we have beautiful weather...in the mid 70's.  What a blessing! 
I'm sharing a card today that I made for a co-worker.  She's leaving to go back to school.  So, I wanted make a card and a bit of a gift, too.

I'm playing along in two challenges today.
The Play Date Cafe Challenge #145.  I loved these colors as soon as I saw the graphic, below.  And, seeing the book & that heart garland made with book print?  Yeah, that sealed the deal for me.  You'll see why.

RetroSketches rs#25.  I play along with their sketches every chance I get, because they're just fun!

I created these ~

A card and 2 coordinating bookmarks.  I already knew that I wanted to use my book print impression plate for this set...that's just one of the reasons that the PDCC graphic caught my eye.  I used the impression plate on both the card and the bookmarks.
If you click on any of the photos, I think you'll be able to see the words from the impression plate.  It's subtle, but really adds so much texture.
For the stamped keys behind the sentiment, I stamped off onto scratch paper once before stamping onto my panel.  On my first try it was just too dark.  I wanted a softer look, so that the sentiment wouldn't be overpowered. 
Oh, by the way, I used one end of a Spellbinder die to cut the top of my bookmarks.  It took a little experimenting, since I couldn't remember exactly how I've seen it done on a other blogs.  It wasn't too hard to figure out and I really like the results. 
I'll list my supplies below, but if you have any questions...let me know.

Thanks for taking a look!
