help with ruffle for apron
 

I am making some children's aprons for a friend. The pattern calls for premade ruffle for the bottom, but I want to make my own with matching fabric. I haven't sewn clothes in so long. How much extra fabric should I add to make a ruffle? I don't want it real gathered.

Thanks for any help you can give me.

A full ruffle is 2 to 3 times the length of the finished edge. So if the edge of the apron is 12", then you need gather 24 to 36 inches for the ruffle.

Thanks. I thought that is what it was, but couldn't remember

It depends of how much ruffle you want. At least twice the length of where you are putting it will give a slight ruffle. An average ruffle is usually three times the length and you can increase it from there if you want it really full.
