I'm not so sure on what you can use but please don't make it to heavy! I have one that was given to me by an elderly gentleman that his mother made some 60 years ago. It's so heavy that I feel to confined and have to kick it off. Now it's folded setting in the closet. But what she done was made one side exactly like the other! there is no front or back, and each square is so think! She put an enormous amount of work into this so that's why I can't part with it, sentimental value for the most part. Good luck on your warm light weight quilt!!
