Center stair step birthday card

I saw a similar scene card on Pinterest (I'm into scene cards lately) and wanted to try it out and make a birthday card to have in my stash.

Here are the steps I made to make this card.
I made a center stair-step card with 1-inch side panels.

Cutting a separate piece of card stock at 3 1/8" x 3 3/8" I used the following SU ink to sponge the background. Starting with the lightest color.

The sentiment piece is 3/4" x 5 3/8"

I removed the sun mask and sponged a little over it to soften the edge.

Then with a stamp from Studio 111 (Michael's craft store clearance for .50) I double stamped the image over the 3 panels.
Bird and sentiment from Stampin Up.
