The best pattern I used was Eleanor Burns~Quilt in a Day, that is not true!

I have also had a friend make me an acrylic template for me to use!

I just did a broken star pattern and ended up with the same problem you had. It looked terrible! As others have said the reason is the bias, 1/4 seam, etc. There is hope though. I blocked it (which is something often done after washing a completed quilt). What I did was wet the quilt in the bath tub and ran it through the spin cycle on my washing machine to get out excess water. Then I used a braided rug and stretched the top into shape and pinned (straight pins) to the braided rug. If you pin it in the correct shape when it is wet it will keep that shape when it is dry. I just finished this quilt (I'll try to post pictures tomorrow), but after I had all of the quilting completed and then washed it, the quilt kept the correct shape without all the puckering. Hope this helps! Let me know if it works for you or if something I wrote needs more explanation.

thank you so much that is worth a try.

It's so soothing to know when one is not alone...

I think it is pretty.

I have attempted lone star twice now - and I get the same result - I think I am being careful and doing everything right - but I always get the hump in the center. Its very frustruating....Hope you get an answer - then I can peek and figure out what I am doing wrong. Good luck.

Go to you tube and watch Sharon Schambers tut on adjusting the fabric in a block. I do not know if it will work with yours but you might try it.

I've never made a lone star and want to. To everyone, thanks for all your input. Now I will try it. To designsforyou, I bet your quilt will look great.

Never tried a Lone Star, not experienced enough, yet.
I am thinking about sewing long strips together. Usually you sew from top to bottom then the next strip from bottom to top. This is so the strips don't get cocky-wompus.

Does anyone think this method would work?

best advice I ever got was... when you sew your large diamond sections together, dont let your fabric 'hang' in the front of your machine. You dont want any drag whatsoever. I sorta bunch it up right in the front of the machine and let the feed dogs do their job. All the intersections are pinned as well.
