Do you want your patchwork seams to match up perfectly every time?
Then you need to nest your seams. Yes, nesting seams is nothing to do with birds and all about perfect patchwork piecing.
Where you want two seams to match up, iron one seam to one side and the other seam to the other side. Then when you put them right sides together to join, the two seams will slot up against each other.
Once you join the seam and open up, they will match beautifully!
