Hi everyone, I just joined but sewing is becoming my passion. So glad to have this forum. Well to my great dismay just now, I was about to wear for a second time this beautiful boucle top I made out of 50 poly/rayon, unlined , Sandara Betzina Vogue 7281 with assymetrical opening and I put contrast piping along front edges….ANYWAY I noticed back seam coming apart in places and when I held it up to light there are seveal places in side seams where holes are forming and its starting to open, where stitches were, Yes I made it nice and snug and fitted….the new look now …but it wasn’t THAT tight. In retrospect I should have used 4 thread serger instead of three but I wanted seams not to be so bulky as its fitted. I perhaps should have sewed another seam with straight stitch along back, side and front panel seams. Now I realize it was more loosely woven than I thought. Before I plunge ahead and try to redo seams I’d like to ask your advice to prevent seams from coming apart again, (PS I can’t line it.) Thanks you wonderful seamstresses out there !!
