I am working on "Stars for a New Day"it is a medallion quilt by Sue Garman...although my measurements are almost exact to the pattern each time I add a row of borders etc, it seems to be "buckling" for lack of a better word...it is not laying nice and flat on the table and I am worried that when I go to quilt it I am going to have problems...why is this happening...I still have the outside star border to add...the very last one..and then I am done..I have been working on this for months off and on...and expertise advice would be appreciated..does anyone else have this problem...is it a "medallion" problem??? (besides an amateur sewer problem...lol)
