I made a blanket with some fabric that is soft on one side and somewhat silky on the other side. I stuffed it with a small bag of polyester fiberfill after flipping the blanket right side out. Its not batting, so I‘m not to sure on how to get it to lay flat evenly in the blanket. The back of the bag says This product meets the flammability requirements of California.care should be exercised near open flame or with burning cigarettes. It doesn‘t say anything about heat, just fire, so would it be okay to iron it on like batting? I really wouldn‘t know how else to do it besides maybe sewing it on but I have no idea how that would work. Any ideas?
Sorry, you are not going to be able to get polyfill to lie flat and stay put on a long term basis. It is not the right product for the job. Use your seam ripper or a small sharp scissors to open up one side of your blanket, buy some batting, put it inside, and quilt or tie your blanket. You do not need a quilting frame to tie a quilt. We lay quilts out on the big tables at church and tie them, using duct tape to hold the bottom layer in place. I have also tied quilts on the floor - even a queen size one once!
Oh denim quilts are the best!! (the last one I made broke my sewing machine). But anyways, ya you will definitely not get very good results if you use fiberfill, especially since you are using old jeans for the denim. Since the seams that hold the jeans to each other are so thick, after a while they will force the fiber fill apart from itself which will make it look like you've sewn a bunch of pillows together for a little while, then after that all the fiberfill will work it's way into clumps in the blanket and it doesnt matter if you tied it or not. It will still do that. Reason being because fiber fill is made to pull apart easily so that it's easier to stuff your pillows or stuffed animals or whatever, so holding it in place with ties or hand quilting or whatever will be completely ineffective because it will still be able to come apart. Your gonna have to take it apart and use batting then tie it. And the other person is right, you can tie a quilt without a quilting frame but I think it's heaps a lot easier to do it with one. And I think it looks better in the end too. I don't know how much you quilt but anyways, I'd just use batting. The blanket will last longer that way and, knowing how much work ot takes to put together a denim quilt, I'd say you want it to last as long as possible. Is this the first denim quilt you've made? Denim is my favorite quilt to make. And lately I've been making only denim quilts even tho in my opinion they are the hardest to make. Anywho, I hope your quilt turns out good!
