How Many Blocks Across Top/Bottom
 

O.K. Girls/Guys I have lost it. I have a quilt that starts out with a LARGE BLOCK in the center, it is 50 1/2 x 50 1/2 (the 1/2 is for the seam allowance). I need to add 8 inches (cut 8 1/2) on the bottom of this large center block for placement of lettering. This would make the large center block 58 1/2 X 58 1/2. I can add more at the bottom to even up the figures, but I can't add less.

Now the fun begins - I don't know how to figure what size blocks will fit on the Top and Bottom of this 58 X 58 inch large block? Do I need to add additional inches to the added rectangle at the bottom to insure (whatever size blocks I need) will fit correctly on the top and bottom? I sure hope this makes sense......... i.e. if this block was 50X50 I believe I would need (5) 10 inch blocks horizontal and (5) 10 inch blocks vertically, (of course cut 10 1/2)
HOW DO I FIGURE A 58 x 58 inch square block? Remember I can add more inches at the bottom to make the figures come out evenly.
Thanks fellow quilters -

if you are only adding 8.5 to the bottom only, your center is no longer square... it would now be 50.5x58.5
is this what you intend to do?

I am confused -

You are starting out with a center block that will finish to 50 x 50 - right now it's 50.5 x 50.5???

Now where I am confused - do any of the attached illustrations look like what you want to do?
(the numbers are for FINISHED sizes)

From one of your sentences, I think it's B - but you are talking about 58 x 58 - so that would be D

It would make more sense to me to add 10 inches (finished) to the bottom because 58 is sort of an awkard number to work with.

58 / 2 = 29
58 / 3 = 19.33
58 / 4 = 14.5
58 / 5 = 11.6
58 / 6 = 9.67

If you add 10" to top and bottom you will have a length of 70" .... 50 + 10 + 10 = 70
so you would need 5 horizontal blocks and 7 vertical blocks
At least if I understand your question correctly.....

I think the OP has to come back and clarify what she has in mind.

THE ILLUSTRATION WOULD BE "B", As other replies mentioned it would be easier if I added 10 inches on the bottom of the 50X50 to make it 50X60.

CORRECTION TO BELOW - I would be adding the extra piece only at the bottom. I agree the figures would be easier to work with if I added 10 inches at the bottom, then I would have 50 X 60. Bearisgray - your illustration "B" would be what I need.

Now, what size blocks would I need to make to go all the way around my 50 X 60 inch rectangle? 10 inch? 10 1/2? or less?

I want to thank everyone for your help and I am sorry I have confused some - I get confused myself, ha..ha..

CORRECTION TO ORIGINAL POST: I am sorry I have confused so many, guess I'm having trouble explaining.

FINAL CORRECTION - THE EXTRA PIECE WOULD BE ADDED ONLY TO THE BOTTOM OF MY 50 X 50 SQUARE. (the square was not 50 1/2.)
I agree the figures would be easier to work with if I added 10 inches at the bottom, then I would have exactly 50 X 60. Bearisgray - your illustration "B" would be what I need.

Here is a diagram I worked out for you. You will need 19 10.5 inch unfinished blocks for the border if you want the blocks on 3 sides. If you want the blocks all the way around it will be 26 blocks 10.5 inches unfinished. Have fun! Luann in CT
