There's no fabric puckering, but it's like the fabric doesn't have the chutzpa to hold the zipper - which is weird cuz it's not wussy fabric and it's been working well for everything else.
I'd really prefer not to have to rip the whole thing out and start again, though I will if I must. I just don't want to spend another 2 hrs on this to find out that my next insertion yields the same results.
- Should I have interfaced the seam allowances? (Again, there's no apparent weakness in the zipper and it lies beautifully flat on the ground. It's when I put it on my body that the waviness appears.)
- Is it that the skirt, around the zip area, isn't tight enough hence the buckling? Should I sew the seam allowances smaller? The skirt fits - isn't loose as far as I can tell. Worried about making things too tight if I do this.
- Should I just use a regular zipper because this thing needs to be more stabilized in the fabric by more stitches? If yes, can I just stitch around the invisible zipper as I would for a regular zipper? Or will that look weird?
Admittedly, I've never sewn an invisible zipper into bias cut fabric - perhaps the bias stretch is encouraging this outcome?
What do I do????
So confused. So demoralized. Please help.
