To make the tiny dots even easier I would consider using a dotting tool made for nailpolish! You can find them really cheap on Amazon. I got a set of 5 double sided ones with all different sizes for super cheap, and they'll make perfect tiny dots.
If you just want to do squares, there's not much to it. 100% cotton is the standard for fabric. Use a 1/4" seam allowance and have at it. Keep in mind that because of the seam allowance your finished square will be 1/2" smaller than you start with. Once you get past that part, I'd recommend reading up a bit before continuing.
Over at /r/quilting they have a pretty inclusive wiki and every Monday there's a "stupid questions" thread. If you like books to help you learn things, my favorite beginner's book is "The Beginner's Guide to Quilting" by Elizabeth Betts. (Amazon link here).

I cannot recommend this enough. It's my second sewing machine. My first was my grandma's from the 1940s then this. Comes with lots of accessories. I bought mine "used" from amazon warehouse for I think $125 because the box was beat up (but the machine and all accessories were perfect and present). I have nothing to compare it to but the 5k reviews on amazon loved it and I have been very pleased with it.
I used this vinyl. Then let it cure for 24 hours.
The unicorn head glitter was from a different place on amazon.
There's a signature ring on Amazon. I'm sure if you could design the silhouettes to fit the ring they could definitely engrave it!
No problem, I also had a really hard time figuring out the "proper" way to get the damn pattern on the cloth! I first trace the outline on tracing vellum, which you can get at craft stores like Michael's, artist supply places or just on Amazon. I use these transfer pencils to trace the outline onto the transfer paper. I don't need a lightbox b/c the vellum is translucent. Then I use an iron to pre-heat my fabric (since I'm still learning, I use these really cheap sackcloth napkins that I also get on Amazon (i'm addicted to Prime), then iron the pattern on! Recently I started taking the extra step of reinforcing some of the pattern with this pen, b/c I find that my own hand sometimes blurs or erases the ironed on lines of sections I'm not working on, then by the time I get to them it's hard to see the exact pattern. The transfer pencil will still be there after a trip through the wash, the blue marker is totally water soluble & will disappear!
I'm far from an expert, so there's probably a tidier way to do all this, but it's working for me. Happy stitching!
