I started in 7th grade and did it off and on through Jr. High. Got an "apprenticeship" at a hippy leather shop in the late 60s. Did a lot of "fix it" for the guys in my Army unit. Started get more serious about 40 years ago. My son made a key fob for my mom about 25 yrs ago that she still uses and his daughter made her another one this last Christmas. All together I've been at it for 55 yrs.
I would say your biggest problem arises from your "dry" time. I usually wait hours between steps. Sometimes as long as 24 hours. Leather is a sponge and it takes time for things to fully cure/dry.
As odd as it may seem, we get little guys like that up here in the great PNW desert. After a really good T-storm, we get hundreds of little guys like this. They don't have red eyes, but they are much the same otherwise.
I don't do ANYTHING metric, so I have no idea how big your awl is. But it is obvious that you need smaller needles or a larger awl blade. The only time you should have any real difficulty pulling the needle through would be when you back stitch.
From the small picture your carving looks quite good. But your basketweave looks rather faint. And I agree, moving the zipper will help make things "flatter".
Looks like nice work. But I didn't know anybody wore wrist watches any more. I don't think I've seen one in 3-4 years. Most folks just use their phone for a watch.
I've carried a pocket watch for decades, because I can kill a wrist watch in less than a day. Construction is really hard on things.
If you have a dog, the "Alpo Variety Snaps" boxes are half again thicker that cereal boxes. But they are glued like they need to withstand a bomb. They make great patterns.
The website looks a lot like our Harbor Freight. HF carries what I call 30/5 tools. If they last the first 30 minutes, they MAY last for 5 years. But I was unable to find any other listing for the brand.
I'm pretty sure that you THINK you are a master of all things. But you AIN'T. You seem to have a comment on EVERYTHING. You aren't all that and I'm quite frankly tired of your EXPERT opinion on EVERYTHING. Your ass is MUTED!!!!!!
When our sled dogs cut cuts/etc on their pads, we put a "patch" over it held on with superglue. It stays in place for several days and keeps the wound clean. Superglue was developed for surgical purposes.
