Question Converting Block Size - HELP PLEASE !

The attached 2 blocks are currently 12 inches finished. Is there a way to resize to a 20" finished block ? Thank you in advance.

Kathie, you can but it won't be easy. The first block has 3 squares to make up the block. 20 inches divided by 3 is not an easy number to work with (6.66 inches). 18 inch block (6" squares) or 21 inch block (7" squares) would be easier to do. And you can get a 19 1/2 inch block with 6 1/2" squares. I'm not even going to guess on the second block because the squares within the block do not appear to be the same size.

The first block is based on a 3x3 grid. When you make the block finish at 12", each piece in the grid finishes at 4". If you change to a 20" finished block, each block must finish at 20/3 = 6.66666". This unit is much harder to measure. Any block based on a 3x3 grid is easier to finish at a size that divides by 3 easily. This doesn't mean it has to be 3 times an integer (3,6,9,12,15,18,21,24,etc.). It could also be in half steps (1.5, 3, 4.5, 6, 7.5, 9, 10.5, 12, 13.5, etc.). So, short answer - I wouldn't try for a 20" block, but would pick something close that divides easily, probably the 21" block.

The second block is a 7 x 7 block. On my screen the corner block measures 1 cm, and the middle block measures 1.5 cm, for a total of 3.5 cm across. That can easily be done as a 21" block, but for 20" you'd have to use decimals.

For a 21" block, the corners would be 6" squares finished (6.5" unfinished), the center top would be 12" wide (12.5 unfinished), but it's not a flying geese unit, I think I would need a template for this one. The center top is divided in thirds in both directions. Probably the easiest way to piece that piece would be to make a quarter square triangle block 12 " square, then cut off the part you don't need. The center square is a snowball unit. It would be 12" square (12.5 unfinished), with 4" finished (I think this would use 4.5" unfinished) squares sewn on the diagonal on each corner.

For 20" you're on your own.

Thank you. I would never have thought of simplifying the process by making the block divisable by 3. I love this board - I have so much to learn !

Thank you - that is a very valid point that I hadn't thought of. I will definitely put your info to work !
