They were so simple and easy to make. Just take your shirt and cut off the sleeves right at the seams. Then cut the sleeves to the desired length by measuring them up to your doll. Remember to allow a few extra inches at the cut part to allow the edges to be rolled over for the elastic to be added. Cut your little half circles on the inside parts of the shirt like I did below. This way you will end up with the buttons on the outside of the pants.
Now to make the pillowcase dress all I did was trim off the collar and made sure the fabric was straight across the top and back. Then cut the arms out by using the seams where the arms used to be sewn on and where you just cut the sleeves off.
Just another quick and easy upcycling project. And what a great way to use up those outgrown hard to part with clothes.
