At last I finished the second pair! It is hardly shorts weather now... After seeing James in the first pair of shorts regularly I decided they were really nice and it was worth making another pair right away (to consolidate the things I learned the first time).
The fabric is probably Ultrasuede. It is certainly very much like a swatch I got from Denver Fabrics, so if it isn't US, it is something very like. As I understand it, Ultrasuede is the USA tradename of fake suede made by Toray (a Japanese company), so I'd be unlikely to see the name here. Anyway, they had rolls and rolls of this stuff on the top floor (5th) of Okadaya in Shinjuku, Tokyo, but only 1.5m left of the particularly thin yellowy beigey one that I bought. Most of the rolls said it was OK to wash but this one said dry clean only, so of course I pre-washed it in the machine - no ill effect. Ironing was OK so I could fuse interfacing (also fused a few other bits with seam fusing stuff - darts and the huge seam allowances at the back crotch).
phew! Glue stick is your friend!!!! I glued everything! Hope it washes out like it says on the packet! I used a water soluble pencil to mark things - hope that washes out too :o. I used this page a lot to work out how to do things.
I did lapped side seams, and topstitched the seam allowances above and below the side pockets to the front to match. Maybe you can see some of these details on the side view. The lapped seams are wonderfully supple.
The waistband I did quite differently form the instructions on the pattern. I sewed the crotch first (the pattern sews on the waistband first), then I cut off the seam allowances from the waistband, laid some twill tape on the inside, and basted on the outside and inside of the waistband with glue. Then I double top stitched through all layers. See waistband. With the twill tape stabilising things the waistband seems more snug than the tencel so I haven't actually added the belt carriers.
I used a snap instead of a button and a plastic zipper rather than metal and I think it help the front sag problem (see last paragraph of original review).
I did not topstitch the inside leg - didn't want to make the seams stiff - they are so nice and soft either lapped or with just a single stitching line. I am not sure if they will hang well with only this one line of stitching - will see once they are washed and worn for a while.
The length is unaltered from the pattern but I cut off the hem allowances and left the edges raw.
