Here's a link to my blog where I have a favorite heart quilt. It's an easy 16 patch block made with 3 1/2 inch squares and alternate heart blocks. The hearts are made with 6 1/2 inch squares and 6 1/2 inch half square triangles. The corners of the hearts are 2 1/2 inch half square triangles.
Here's the instructions for the heart block. I make mine differently because I use the Accuquilt Studio to cut things so there's less waste with the corner blocks, but they turn out the same.
This quilt would be great for a boy or girl. Most charities need lots of boy quilts because most quilters are women and we like to pick out flowery fabrics. Sometimes we forget boys need quilts too. I'd like to encourage you to make 2 boy quilts for every girl quilt this time around, just because boy quilts are always in such short supply and it makes you think outside the box. I'm going to make another one of these, just because I love this quilt so much.
