*Sorry about the comments--I think it's better now. I wondered why it was so quiet.
Today, I installed the zipper on Eris, and I did it on the first try. Long-time readers will know that I HATE sewing. Mostly because I suck at it. Part of the reason stems from the fact that I don't pay attention to the little details (like I do with knitting) and part is general ineptitude. However, today, with the help of a lovely locale (the cottage) and my super-fab mother-in-law Marilyn, seamstress extraordinaire, I figured it out and finished Eris.
I carefully documented each step as best I could to share with you. So, here's how to sew in a zipper.
Step One: lay your cardigan on a flat surface like a table with the right side facing and line up the edges. Your garment should be washed and blocked.
Step Two: Using a contrasting yarn, baste the opening of your cardigan closed. Be sure to catch the same stitch on each side (ie the same one in from the edge) so it's the same on both sides. When you're done, turn the garment inside out and lay it nice and flat like before.
This was the excellent advice of my mother-in-law. With the front sewn closed you can be sure edges line up and your zipper will be even on both sides (my usual problem--one side is not the same as the other).
Step Three: Lay your zipper (wrong side up) on your zipper facing and pin it in place. Then using contrast thread, baste it in place near the teeth so it will stay in place. You can also baste it on the edge too if your paranoid or just thorough.
Step Four: Using your garment-coloured thread sew the zipper using an overcast stitch along the edge of the zipper being sure to catch the same vertical stitch along the edge. On this sweater it's easy because it will be where you sewed down the zipper facing. There's no picture because you can't see the thread-looks just like the one above.
Step Five: Turn right-side out and undo your front edge basting (the yarn one). The zipper is perfect oui? If so, sew another seam using a backstitch up the middle of the zipper tape along both edges for extra stability.
Step Six: Remove remaining basting and bask in your sewing perfection (though my photo skills need work).
Tomorrow: Pictures of me wearing Eris. Marilyn and I decided to celebrate the sewing achievement with some Bloody Caesars (extra spicy) and it was dark by the time I remembered to take photos!
