Beautiful bag! I love the single strap design and the outher pocket! Good work!
I also recently began making handbags.
To Linda: I always found it helpful to examine closely items that were already made. You can learn a lot by examining how ready-to-wear garments were put together. Same with purses.
A few weeks ago I bought a bag at the Salvation Army store to take apart. I wanted that design as it had the center divider pocket in the lining. I ended up taking the bag apart and making a pattern from it on non-woven patterning fabric.
I still kept the original bag as that shows me how it was put together.
I still work with woven fabrics but have a lot of experience with leather. I have a pair of suede slacks I never wore and am considering turning them into a purse.
I have made most of the bags in Butterick 4409 pattern. Lots of small pieces and some bags easier to make if you purchase ready made handles and other notions needed. Also, iron on interfacings work so well.

My first project was hand sewing on crinoline fabric to make dresses for seven inch character dolls. I had received the kit as a Christmas gift. I still have those patterns somewhere!
First real garment, after so much begging, was a pattern and fabric for a cotton dress and jacket. Mom was so skeptical that I would finish a full garment! I remember that the seam widths were less than 5/8" as one of the seams raveled out when I wore it. The notched collar on the jacket was poorly turned. At this age, just could not trust the term 'clip in'!
