This is an easy and extremely non-technical Valentines Day repurposing project. I turned an old t-shirt into this ruffle heart applique for a kids t-shirt.
The supplies for this project are:
1 old t-shirt cut into round circles (about an inch and a 1/4 in diameter)
1 heart shape
Iron on transfer paper like Wonder Under
1. Start by cutting all of your circles, tracing your heart shape onto the Wonder Under and ironing it onto the felt. There is not a precise number of circles to cut because it depends on the size of heart you use but you need quite a few so make sure you pick a t-shirt that you can cut lots of circles from so that you can cut more if you need to. Cut the heart shape out as well and peel off the paper backing. You want to give the adhesive side a chance to dry a bit before starting to sew because otherwise it doesn't run through your machine as smoothly.
3. Hold these in place on the heart (keep at least a 1/4 inch away from the edge of the heart) and stitch 3 or 4 stitches up and back and then repeat.
6. Remember to stay about a 1/4 inch away from the edge of the heart as you add pieces. I kind of fill one side of the heart and then the other.
