I am hand piecing. Do I press the seams after it has been sewn? If so do I press it open (half to each side) or all to one side. Or do I wait until the block is done and then press the seams to one side or the other depending on the color (towards the darker side)?
If there is no right or wrong answer here - tell me what you do and why? My block is Windmill 2 (mostly triangles)
