If you have the option of putting your name on the title header (bone jeweler by Your Name), do it. I could swear I saw your real name posted on one page or another, but I can't find it again. You have Bone Jeweler, Grygon, and... Colleen, was it? This identity crisis doesn't make a connection with your audience. An artist looking for patronage needs to make that connection. Maybe you don't like your name, but as you age, Grygon may not age with you. Just sayin'. And put your name in your "about" page, and so on. All I'm seeing is I and me, as if you were an invisible person.
I think you might look into making a video or two when it comes to some of your more tutorial-like posts.
Outside of the bloggy parts, the site seems more utilitarian than engaging, so I would put the blogging stuff front and center and put everything else in the background. The "home" page is completely unnecessary and just delays getting to the good stuff. Also, you should decide where you're going to sell from and just do it. It's hard enough to promote sales when you have one outlet. Promoting 2 takes away from other stuff you could be doing.
If you put the blogging articles on your front page - the content people would be interested in - with a more obvious SHARE THIS sidebar on every page, then you will more likely get some shares from visitors. I would delete the language about supporting yourself and feeding your family on the purchase items or wherever else you have it. No one wants to come to your site for a guilt trip. If they want to read about that, they can go directly to the Patreon, which is pretty obvious what it is before you get there.
As far as not being impressed by the taste of your recipe, when you're working on a recipe, you can mix the sausage ingredients, then cook a small sample of it. Taste and make adjustments. I know too many cooks who follow a recipe and NEVER taste the stuff before it's all cooked and ruined. It's hard to say why you didn't like the recipe you used. Could be a lack of a particular flavor you were looking for, could be you just needed a bit more salt or even sugar. Hard to say without seeing the recipe.
Using low-fat meats can be overcome by the inclusion of wet ingredients, like finely chopped zucchini (which is pretty flavorless, but has a lot of moisture), or a little well-cooked rice which retains moisture and also takes on the flavor of whatever it's with. If you like a little sweetness, you can use grated apple or pear.
If you'll be washing it before the embroidery takes place, and the sewn-together top consists of only one type of fabric I would say, sure, go ahead and sew it together then wash it. Otherwise, you could zig/zag or serge stitch around each square (that has to be done anyway, so it's not extra work), then wash, then sew together.
When you're inexperienced, everything takes longer. That means custom work is typically always going to be more time expensive because you're approaching a job without "experience" of having done that particular job before. However, you can't charge people for your inexperience no matter how much time you spend on a project. If you don't want people to drop you at the end of a project or get a bad reputation, you have to give them a very good estimate up front so there aren't nasty surprises for them or for you.
The more projects you do, the more opportunities you'll have to figure out how to cut your time down. That's true with any craft, business, or job. Meanwhile, if you're able to figure your materials costs, charge for that plus whatever you think you can live with to get the project out the door. Maybe create a few different levels of project pricing based on the amount of detail in any particular project - increments of $10-25 for example. Once you get that established, stick to it - otherwise, you're back doubting yourself again.
One thing about good craft blogs is that there are tutorials galore. Tutorials are very, very tedious to put together. However, if you want to rank, you have to do it.
Another way to do it is just to become a referral/resource site (a corresponding pinterest and/or tumblr would work well there). You could link to other sites that have the tutorials you like. I would put "with free tutorial" somewhere in the title of each post so folks can easily spot them when browsing.
