DIY  ” how to make ruffles”

Sewing on the side of the fabric with the widest part of your machine 2 parallel lines developed.

Here the wheel that will pucker. For beautiful pleats: multiply by 3 the width of your base for light gathers multiply by 2.
On this tutorial I multiplied by 3.

Take 2 son from below (WS) and gently pull the son together, oh beautiful pleats!

pin location on the wheel location based, although evenly distribute the gathers

Here are more closely

Stitching straight stitch width to 2.5 to 3 between 2 son puckering.

Shoot the son of 2 below as to frown, but this time it is to remove. Remove all the son puckering.

Beautiful regular gathering. Easy is not it? I await your comments;-)
