I have a collection of fabrics that I take out, look at and put away again - too chicken to cut and sew, not sure enough what to do with them. This top was made with one of those pieces - it was a big piece of fabric and I always thought I should make something "big" out of it to fully utilise it.
A year has probably gone by, and I chopped it. This Butterick 6598 top took about half of it.
I followed the pattern but made these modifications -
slightly widened the torso from the waist down
put slits in the side
put slits in the arm seam
These would have been unnecessary if the pattern had been my size or if I had remembered to cut the arms and sides a bit bigger in the first place!
