My two daughters are receiving these hearts for Valentine's Day. Start to finish they take about an hour. Don't make the same mistake I did and knit two and try sewing them together. You need only knit one and sew the edges then add stuffing. They are adorable and not too difficult.
I also made these piece of cake heart garlands. Simply cut out heart shapes and sew them together through the middle. I hung one on the stairs and one on the mantle. Beautiful, easy and inexpensive!
