Overlocker Gathering

I have been trying to get gathering right on my overlocker for some time. I have searched all over the web for tutorials but non have quite done it for me, it has always ended up being clumpy with a very uneven gather. This evening I came across this blog here which gives straight forward advice on how to achieve nice gathers using an overlocker (or serger to some).
Tried it, it works. La la la!
All gathered.

Attached to straight ungathered fabric. I used black thread so that I could see how the stitches are forming.

Right side of fabric. I am all ready now to make a little dress for my granddaughter, I just have to decide which fabric I can live without in my stash to make it!
