Hi everyone! It's that time again! Time for another linky party, or link up, or whatever they're technically called (have you noticed I am always shuffling through names). lol. Anyway, I was thinking about the Giant Granny Tutorial that I will be sharing soon and thought it would be fun to talk about the beginning of that project today.
Do you remember when the rave on blogland and Flickr was the Granny Square? Ok, it was only a few months ago and I know everyone is still making them, so it still is. What a fun design! Thank you Jolene of Blue Elephant Stitches for showing us all that great tutorial!
I knew I wanted to jump on the band wagon and make one too, but I knew there was NO WAY I could ever make a whole quilt of them. My time and attention span would let it turn into a UFO to waste away on my project pile. lol. Then I thought, "well then, I'll just make one! and make it big!" I don't know if that's what I really thought, but that's what I did.
I could have just taken some really big squares and put them together, but I wanted more variety and interest than that. I think it would look great with super sized blocks if you had the right fabrics, maybe some London?! yes please. But that's another story.
So I went to work to figure out my measurements...
I thought I had it figured out. But low and behold it turned out smaller than I wanted. With a 5" sashing It finished a decent size, but I still wanted it bigger.
I decided to try again. Let me tell you, it was a mess! I do alright with math, and always seem to enjoy some quilt math, but this was not working. Trying to figure out the diagonal and length and what I needed my tiny squares to start out as was hard. More and more time went by, along with lots more math, and I couldn't get it!
I wrote this email to my dad, who is the math king, I read it now and I don't even understand it. ;)
I have a math question for you. I've attached a picture that I need to figure out the formula for. I'm wondering if you can help me.
Here's what I'm looking for. There is the entire design which is the large square, then each solid color makes up a medium square. Each medium square is made up of 9 smaller squares of the same color. So 13 medium squares. If I know how big I want the complete square to be - say 50" x 50". How do I figure out how big to make the medium squares? I am having trouble figuring it out since they are turned on the corners. I thought I figured it out and made a quilt that ended up being quite a bit smaller than I wanted. Once I know what the medium squares need to be, I can figure out the smaller squares easy enough. Is there a formula to figure it out? Like if the sides of a square are Length x, then the diagonal is y? or visa versa (which I guess is what I need to figure out... the length from the diagonal.
Does that make sense? :) I don't know how well I explained that. :)
Thanks for your help! I love you!
then I sent this email:
Ok, I tried again at this and think I might have it. I figured an equation backwards for figuring out the diagonal length from the side length. I measured different squares and found that if a square is 2" long on the lengths, then it is 3 7/8" on the diagonal. So if the diagonal length is D, and L is 2", x is how many L you need to get the length of your square ( for example xL = 2L = 4" square). Then here's my equation:
D = xL + 1/2(xL) - 1/8(x)
And if S is the size of the complete big square, then D = 1/3(S)
So then if I want S to be 50, then D = 16.5 (really 16.6... but I just rounded to make it easier. it doesn't have to be exact)
16.5 = xL + 1/2(xL) - 1/8x
then 16.5 = x(2) + 1/2(x)2) - 1/8x then if I take the x out
16.5/x = 2 + 1 - 1/8 - maybe this is wrong??
16.5/x = 2 7/8
x = 47.43
That can't be right can it? I think I messed up somewhere. It's been so long since I've done any algebra. Can you help me out?
then here was his reply. lol.
I don’t know what you are trying to figure out? If it is a square then the diagonal is square root of 2 times the length. If it is a rectangle then you square both sides, add the squares together and then take the square root to find the diagonal. If you know the diagonal then you go backwards from above, ie. the length of a square is the diagonal divided by square root of 2. What else are you trying to figure out?
yeah, I don't remember anything about square roots. Anyway, so instead of all my confusingness (word?), all I needed was the square root. So there's your answer.
So now to my final, and correct figuring...
but that's all I can show for now. This Granny Quilt is going to be BIG! I decided to Go Big or Go Home! :)
Anyway, this is the project I was wondering if anyone would want to do a quilt along with me. I am going to share a tutorial for my smaller quilt, but I've figured some good tricks and tips for putting this big lady together to make it go MUCH faster, and thought it might be fun to do with others. I'm not finished with it yet, so I don't have a final preview, but then isn't that what Quilt Alongs are all about?!
So there is my story of my blank pages... going from inspiration to paper to lots of paper to some fun quilts and beautiful colors, and perhaps a quilt along! Oh the possibilities!
What are on your pages?! I'd love to read your stories. :)
I just ask a few things:
- only share a project in the beginnings. It can be something that you made a long time ago, or maybe came up with a long time ago but yet to have started on it, or a brand new idea. Tell us where it came from or what you want to do with it... or just share a sneak peek! Those are fun too.
- Make sure to link back to my blog in your blog post so others can also come join the fun. Grab the button from my sidebar for extra brownie points. ;)
- Link to a specific post, not just your blog.
- Stop by and say hi to other people on the list.
Thanks for playing along! :)
