I'm sorry I ever thought (or voiced aloud) that I would never use math in my daily life. Sure, I'm not sitting around, doing proofs, but I am using math. Forgive me.
So yeah, this is probably stuff you know, but I thought it couldn't hurt to include some tips on cutting shapes.
I actually was inspired to do this post because I got an Accuquilt Go! Fabric Cutter for Christmas! It was one of the only things I asked for, and I'm so excited! What that means is that I will be able to make perfect circles every time (oh boy!). But not everyone had a rockin' Christmas like me, so here you go.
Since we're on the subject, let's talk circles.
First determine how wide you want your circle to be (the diameter). Divide that in two (to get the measurement of the radius). I'm going to cut a circle with a radius of 3.
Now use a fabric marker to make a mark. Take a ruler and measure out from this the length of your radius (for me, 3 inches). Make a little mark. Shift your ruler slightly and make another mark, also 3 inches from the center.
Keep doing this till you get back to your original mark. Now you have a dotty circle to cut!
Well, hello, beautiful!
Yeah, I'm using super cool math language. Word.
In case you've forgotten, though I'm sure you haven't, this is a triangle that has two equal sides (and angles). Here's a really (REALLY) easy way to cut those...
Remember this equation: a^2+b^2=c^2 ? You don't? That's ok because I jest... we don't really need it, but did your algebra anxiety hit you for a moment? :)
It's way easier than that if we cut our triangle on the fold. How long do you want your triangle's sides? I'll make mine 4 inches. First, I want to cut the side that's perpendicular to the fold. Since its folded, I'll cut it two inches. Now I just take my ruler and place the end at that spot. Then just move it around till that side's going to be 4 inches.
Ain't they just lovely? And so easy to do. :)
