I love these simple Heart Wreath decorations.
All you need are some card scraps (I used old packing boxes) and some cheap wool/yarn.
Draw out a heart shape on your card and then cut out the center leaving about 1cm heart outline. I find it easiest to fold the heart in half and cut out the middle with scissors but you could use a craft knife.
Start wrapping the wool around the heart shape. I do the heart in two round. The first time around, I leave some gaps and try to get the wool sitting as neatly as possible. The second time around you can focus on filling in all the gaps and the wool is less likely to slip as it had the wool underneath to grip against.
Tie the end of the wool off in a loop and hang.
You could have fun adding some embellishments but I love the purity of the hearts with just the wool or ribbon.
Sometimes simple is best.
