Hearts like these have been popping up all over the place and I'm sure you can find tutorials and instructions for something similar if you look. I started with a bunch of pink 2.5" squares that I had already cut - they are the basis for the single Irish chain baby quilts I frequently make. Sew 3 pink and 1 white/background 2.5" square together to make a 4-patch block as shown below. These little 4-patches should measure 4.5" unfinished. Don't worry if yours aren't exact, you'll just have to make some adjustments as you continue. Add a 1.5" strip of white/background 4.5" long (or the actual measurement of your 4-patch) to one bottom edge of the 4-patch. Press toward the white! (I don't press to the dark side all the time!) Then add da 1.5" strip of white/background 5.5" long (or the actual measurement of your 4-patch plus the first white strip) to the other bottom edge of your heart. Again, press towards the white!
