When 4 seams meet I always get a thick wad of fabric and looks like a lump on the right side. How can I make it lie flat? Thanks in advance for any help you can share.

Are you pressing your seams open? I have found that helps eliminate some of the bulkiness when 4 or more seams meet.

Press the seams open and put a couple drops of water in the bulkier area of the seam, front and back, and then press. :D:D:D

Eleanor Burns does her centers like this=

That is how I learned to do mine. It does make them lay very flat.

i snip those seam allowance threads and then finger press open, giving a little twist, its the elenor burns method.

press open or opposing

Thank you for all your help -- my problem is solved, the Eleanor Burns way!

This is how I do mine. Works great and kind of fun to do!
