This was one of those projects that I began in 2012 but didn't finish until just recently. Actually by recently I mean 3 weeks ago! It's a top that I morphed together from two patterns, and made some tweaks here and there to get exactly what I was looking for.
New Look 6713 The pattern provided for an a-symmetrical or cow-neck front, neither of which was what I wanted, so I took the a-symmetrical pattern piece and cut it on the fold at the centre front so both sides were the same.
On the back I didn't just want two straps which would look as if I was going to the beach instead of work, so I took a back pattern piece from another pattern and used it as a template to create the back, matching the side and shoulder seam pieces to the front piece.
I'm interested to hear from others on their success with morphing patterns to get what you want rather than looking for a whole new pattern.
