Gusset length

[Danotriglide]

Good morning everybody!

I’m working on a small bag about 8”x12” and need to learn how to figure how long the gusset has to be. I tried laying a waxed thread all the way around the side piece like the video showed but it came out way too long, like 2”. Sooo…..I’d like to get it closer the first time. The sew line will be 3 /16” from the edge so does that mean the dimensions are now 7-5/8”x11-5/8” ? That makes sense to me….

Any sound reliable advice will be greatly appreciated! 

HELP!

P.S.

Thought I should say the panel will overlap the gusset, panel on top.

Trying here too…

I posted this question in How To but no one’s stepping up. 
I’m making a bag 9”x5-3/4” of 2mm thickness leather. I’m stitching by hand and have layed out and punched the holes about 3/16” from the edge. The 4 corners have 1” radius. My search here came up blank so I’m asking…do I add all sides together and subtract the circumference of the 2” diameter or work from the dimensions of the sewing line? I tried the old string around the outside all the way around and the string layer over the sewing line. Outside strings 1-1/8” longer. I’d like to learn how to get it right the first time and not trim it to fit or piece it together. 
 

Thanks!

PS

I’m laying the outside panel on top of the gusset.

Do it however you want . . . but if my project requires a gusset . . . I lay down the item . . . trace the outside for the length of the gusset I want . . . then cut the outside of the gusset piece out of a hunk of leather.

I then decide how wide a gusset I want . . . use a pair of dividers and mark that all around the inside of the piece I cut out 

I then cut out the gussett . . . glue it in place . . . sew  /  lace / stitch /  as necessary.

May God bless,

This guy says subtract an inch from your measurement for gusset length.  Some day I'll test this using my heap of leftovers from bridle sides but I currently have no experience with bag making.
