I had a lot of left over scraps of fabric. Luckily enough to cut out strips or squares and from the smaller pieces a heart or bird. Be creative and sew some strips or squares together. I also had a piece of lace that was the width of the sheet. Embellish the way you want. Play with it before you attach everything.
Here you see that I attached green and checkered pink/white squares at the top of the linen. To finish the edge I stitched a white,lace biais.
This is the heart I hand sew on the green squares.
Strips of fabric stitched together and in one of the seams I stitched some lace. I did'nt finished the edge, I left the seamy side the way it is.
