Janice McC, I had the same learning experience. I didn't have enough contrast between my light blue primary color and medium blue background. I intended in the beginning to use three shades of blue, but ended up changing the dark blue for the secondary color to red/orange/yellow. I'm making it for a wedding present and found out the bride likes bright colors... so all blue didn't seem the right thing to do. In the end, I like the change of the secondary color, but sort of wish I'd used the dark blues for the background instead of the medium blues.
