I recently made an 8" finished block, but now I want to make it into a 16" finished block. I thought I could simply double the measurements, but that didn't work. How is this done successfully?

take each part of the block and subtract the seam allowance. that leaves you with the real size, if you will. Double that then add the seam allowance back and you have the cutting size. So, if you have a 4-1/2" unfinished square in the block, subtract the seam allowance of 1/4" on all sides (totalling 1/2"). That leaves you with a 4" block. Double that, 8". Then add back the 1/2" you deducted and cut the new piece at 8-1/2". that will result in a doubled size block.

What block, maybe someone can help do the math.

nycquilter, This is what my husband said after he saw what I had done. I haven't had time to check it out, but it does make sense to me. Thanks.

The block was in the Thimbleberries book 'Pint Size Traditions' and it is called Flower in Bloom.

This is the way I enlarge patterns. I use graph paper and draw the block to actual size, then add the seam allowance to each component. It helps me to actually see the size of the parts.

Can you post a picture of the block you did as I am not familiar with that one,

If it is a paper piecing block, I use PosteRazor for it - it's a free program online and is absolutely fabulous. Without it, I would be totally lost.

It is just a regular pieced block, but not a traditional like a churn dash. It looks like a flower that is spinning around. I am not good at putting pictures online, but perhaps I should try again.

yes please
