So, I've felted sweaters before for small sewing projects without any real issue. This time I decided I wanted to felt yardage because I want to make a little boiled wool coat for my son. Well, I got a 98% wool fabric at Joann's washed and dried it on hot about 5 times. My research on the internet seemed to indicate that a 98% wool should felt fine. It felted, however it has come out a little uneven. Parts of it shrank perfectly and lay flat, but then other parts rippled. The flat and ripple parts are very consistent and run in lines parallel to the selvedge each being about 3" wide, so the fabric is now striped in a way. This is really seems to be an issue related to how the fabric was woven based on the consistency (even though it is so weird how consistent it is).
I've thought about taking an iron to it with lots of moisture and steam. I'd put a wet towel over it anyway to iron the wool and prevent it turning shiny on me.
I've been really into dot and circle quilts lately. I've been able to master several "patterns" from books (both quarter and half patterns), but now I want to graduate to creating my own designs. I have a wonderful design all laid out. I think the easiest way would to piece half circles and then sew them together.
However, I'm stuck...how to I figure out the correct diameter of my circles to cut, how do I make sure they fit into the outer curve piece?
I think this quilt would be good for a beginner to quilting, but not a beginner to sewing. If you've got good experience sewing clothes, I think this quilt is suitable for a beginning quilter. If you have no or little sewing experience I don't recommend it.
Machine piecing curves is a little tricky, but not terribly so...it would likely cause quite a bit of frustration to the beginner I think.
You could also cut the templates out and sew a block or two before investing in the fabric and time. If your test blocks come out well and you've got the hang of it, I would do it...if not, it may be good to start on a quilt with no curves.
