For a festive take that isn’t too cutesy (think plastic hearts glued to a sweatshirt) try this hand-embroidered sweater that takes less than an hour to complete.
The sweater was on $7 clearance at JC Penney. The iron-on patches were $1.50 and the thread was $1, both at Walmart.
To get this look:
Put on the sweater and mark where your elbows hit.
Cut two hearts (ours were about 3 inches, but I have little arms.)
Iron them onto the places you marked.
Blanket stitch around the patches. To avoid sewing your sleeves together, use a can—I used bathroom cleaner—in the sleeve to hold it open.
The total time was less than an hour.
