I am working on a wedding dress that has draped tucks covering the bodice and was curious... mine are folded down vs upwards, but all I have seen are upwards facing tucks, does it matter? Also, in stitching them down, is it better to sew the entire length or tacks in strategic places? I have previously sewn along the length on chiffon tucks but they puckered and I want these to lie smoothly against the bodice.
