I am trying to make a template for the 25 inch 9 degree ruler...how long is it? what is the width at the top? at the bottom? I have made a paper template and want to see if it is accurate...? Or is it possible for someone to scan a tracing of one and send it to me....?
I didn't mean to put this topic in classified and don't know how to put it in main..?

I have also wanted to make a degree ruler out of paper. I just want to see if I am going to like using it before I buy an acrylic one. I'd also be interested in knowing the size... I was going to ask my husband to figure it out since I know he could (engineer... match and science whiz) but I worry that if he's off by the least bit.....

I know that there will be 10 wedges at 9 degrees and 9 wedges at 10 degrees in a 90 degree angle, which is one quarter of a circle and I have a paper template but I don't know how long the rulers are, how wide at the bottom/top....that is all I need to know...I ordered my pattern last night so when I get it, the instructions may help me figure it out, but if anyone can tell me the measurements for the 2 rulers, I would appreciate it...

the ruler can be any length. the angle is determined not by the length but by the degree between the two lines where they meet at the center of the circle. let's see: if you have a plate and you divide it in quarters, then where the lines meet in the center would create 4 - 90* angles. if you divide those lines in half again, you get 45* angles, etc.
when added up they will total 360*. when divided they become 4 - 90* (or 8 - 45*'s or so on) degree angles. with me so far?
now, if you do it with a little saucer, it will work. if you do it with a huge round platter, it still works. that's because the length of the angle (ruler) doesn't matter.
i have a long ruler to accommodate any length. i simply tape-mark a shorter distance on the ruler if i need to.
edit: for testing purposes, remember that there are 360* in a complete circle. how ever many wedges you want to use MUST add up to 360*. that should help you determine how many degrees you want your wedge ruler to be. decide how many pieces you want to cut and sew.
edit edit: i see what you mean. the measurement at the tip of the wedge is zero. the measure at the wide end is determined by the length, which is always different, depending on how far out you intend on using the ruler. how far out ill you be using it?

I'd like to make my mother in law that tree skirt to start with - and if I enjoy making that, I'm going to buy the ruler - the big one so that I can make really big circle quilts :D
I cringe at buying the ruler and then finding out that I don't like using it at all... but I have a sneaking suspicion that I'm going to like it.

if that's the project you want to start with you can do this:
cut out one-quarter of the circle you want to make. it will be a 90* angle. fold it into as many pieces as you like. if you choose to fold it into 4 pieces, for example, then 16 pieces would make the entire circle. if you fold it into ten pieces, then you need 40 pieces for the entire circle. what you do for the one-quarter, you have to multiply by 4 to get the whole amount.
when you cut the tree skirt to it's full size, you'll know how wide each wedge has to be at the widest point, depending on how many wedges you use.
when you decide on the number of wedges you want, cut out that paper wedge. now you have a pattern for the correct size wedge. trace around it, adding the seam allowance. remember to cut the right number. at one point in the skirt, do not attach the two wedges, but bind it as you would a quilt, or leave it open and turn it right side out, envelope style, as you would a quilt. you might want ties to close it up. btw, this is like a dresden plate, so you can scallop the edges or make points in the same manner.
if you think you aren't going to use one of those rulers more than once or twice, this is very easy. those rulers are pricey.
