I've not done these myself,but they look easy enough.If you google"sewing balloon shades",there are a lot of free instructions,and i think that is all you need.Because as with a lot of these type things if you buy a pattern,that's all you'll get are instruction sheets,because all windows are different.So why pay 15.00 for a pattern if you can get the same thing for free??JMO

I use Singer's books, Sewing for the Home and More Sewing for the Home for any kind of home dec project. The directions are easy to follow and they walk you through the whole process from measuring the window etc. I got alot of bang for my buck - each book was about $12 and I've used them so much they fell apart and I had to punch holes in the pages and stick them in a 3-ring binder!

I would Google balloon shade instructions for free directions. They're not difficult to make, especially if you skip the lining.
