Joyful Hearts book of colours

I have been playing with fabric in order to create a little book of hearts for my youngest grand daughter.  It was created to help her learn her colours.  I created two rectangles using neutral colours - black, grey, brown and white.  I cut four rectangles about 11" x 5.5" - one of each colour.  That configuration gave me eight pages to work with so I went with the basic rainbow of colours - blue, green, yellow, orange, red and purple.  I created a little colourful patchwork for the front.  I cut a template from paper and traced it on the back and cut it out.  I chose fabrics from my stash for all the other colours as well and cut hearts from them as well.  I laid out the pages and then added the hearts in order of  the rainbow which also reflects colour theory in that blue and yellow make green, etc.  I used coordinating thread and a zigzag stitch to attach the hearts to the pages.  Next, I stitched the pages fronts together - black to gray and brown to white leaving a gap to turn them inside out.  Once pressed I used coordinating thread to add a double row of stitching to the edges.  Next, I did some all over stitching to more firmly attach the fabric to each other which stiffened the pages a bit.  

Unfortunately, I failed to properly position all of my hearts back to back on my pages so when I did my all over quilting I ended up stitching over some of my hearts.  A bit of a bummer but I had not anticipated the problem so I did not plan for it.  I will do better next time.  Fortunately, it was on only two of the hearts - the blue and the orange and I was able to camouflage the error with a Sharpie markers in the right colours.  Youc can see below how I coloured the light thread with  blue where it ran over the edge of the heart.  The back page has a pink heart.   I laid my two pages over each other and ran a row of zig zag stitches down the middle to create the spine.  The hearts seemed a bit flat so I handstitched a heart on all the colour pages with coordinating embroider floss.  I had to be careful not to stitch too deep which was not too difficult.  

I am really happy with how it worked out and I hope she will enjoy playing with it.  She is a year old and taking her first steps!!  Therese
