You can make them any size you want. Just think about what size you want your quilt to be. Queen is around 90" X 108." If you wanted to use a layer cake (10" squares), they would make a 9" finished HST. 90" divided by 9" is 10 squares. 108" divided by 9" is 12 squares. So without borders, you would need 9 X 12 = 108 HSTs.

What size squares to you want?

oh wow ....your awesome !! I suck at math ....... i was thinking around 6" blocks ?? Trying to figure the bast cost effective way .... layer cakes , but wouldnt that be alot of waste for a 6" block ??

If you want 6" squares, for that size quilt you would need 270. Don't forget, that is the finished size, so you would need to make 6.5" HSTs. I would cut 7" strips (then squares) from yardage, and try a test block first as you may need to use 7.25" squares.

Yes, I like to add the extra 1/4" and square up, too.

If I do this sizing , I will only need 1 layer cake ...... So it would be 12 blocks by 10 blocks ?! What is the 9 x 12 you mentioned ?! THANK YOU !

​​​​​​No wait .... ( my dumb math ) ..... if a layer cake is 42 10" squares ..... and I would need 120 ( 10 squares by 12 squares ) 9" finished HST 's ........ then I need 3 layer cakes ???!!!

Just to throw another wrinkle into your puzzle--the pattern you linked, uses a constant background. That means that you will either need yardage (the least expensive option) or a plain coloured layer cake. So if one thinks of yardage and 10 inch squares, in a perfect world, you can get 12 from 30 inches and 60 (one square will make 2 blocks) out of 150 inches--that's just over 4 yards.

So, for 120 HST's, you would need only1 1/2 layer cakes but yardage too.

But also, the size 90x108 would be if one wanted a pillow tuck. I make my queens only 90x90. That also means that they can be turned so that all edges will get the same amount of wear.

The 9 X 12 is 9 squares wide by 12 squares long = 108 squares.

So you need 54 print squares and 54 solid squares. There are 40 to 42 10" squares in a layer cake.

If you wanted to add a border, you could make your center 8 squares wide by 10 squares long. Then add a border to make it the size you want. That would be 1 pint layer cake and one solid layer cake.

Wouldnt you mean "wrinkle in my QUILT " ?!! LOL !!!!

YES !! I have a few yards of a solid , and I ordered 2 layer cakes ... now to sit on my hands until they arrive !!!!

I SO appreciate y'alls help and knowledge ....cant tell ya how many times I goofed my math and ended up with an "original " design !! THANK YOU guys !!!!!
