It's the end of Day 1 of the jeans construction period - and I've made serious progress - and some decisions:
1) I finished the front pockets - I used a twin jeans needle to topstitch - and I'm fairly happy with how these came out.
2) I finished the zipper - I used both JStern's blog but mostly relied on the clear directions and I am happy with how the zipper turned out.
4) I finshed the back flat-felled crotch curve seam. Jennifer's directions call only for the yoke to be flat-felled but I went ahead and did a 3/4 flat felled on the curve seam also (the directions called for 1/2 seam) and again, we shall see how this turns out. I originally very much disliked the flat felled construction but after a night at the movies obsessively staring at the back of everyone's jeans I've determined it's not so bad. And, because of this particular denim - I don't believe I can tear out the seam without disturbing the denim (little white threads have begun showing up where I did re-do a portion of the flat-felled seam).
5) Based on my failure in the flat-felled seam area - I've now determined to put in 3/4" seams versus 1/2 (since I've lost weight and the muslin was a bit looser) and NOT flat-fell but to top stitch with the dual needle on the side seam and inseam. (J. Brand jeans does this).
6) Here is a depiction of a 3.5" zipper I bought from Jennifer at ASN (actually I bought five!). It's a YKK zipper, excellent for jeans and reputed (I cannot yet verify) to be environmentally conscious. I'll investigate that further.
Tomorrow: Sewing inseam and outer seam; construction of back pockets on the jeans, and waistband. Monday: Rivets, buttons and hems! Jeans Ho!
