circular needles in a bag

I have several circular needles, but I have a serious problem : how do you keep them tidy ?  I tried a bag, a box, but somehow they get all messed up.  Don't you hate it when you are looking for a 4mm 60 cm one, and can only find a 5 mm 80 cm one.  I was desperate for a good system to put them carefully away.
At Knitpro or Prym you can buy these expensive cases, really nice, but I wanted something personal.
That's when I found a reference to a pattern by Butterick,  to make your own case.

I ordered it, paid through paypal, and 2 days later the pattern fell into my letterbox.  Great service !
half a day behind my sewing machine, and this is the result :

it's slightly stuffed with interfusible filling

Sesam, open up

Tada ! all the needles are safe, and in clear sight

the points have their own place

I put a little paper with the size and length visible

ready to be taken anywhere now.

I kinda like the big bag on the front picture too. Maybe I could make it to put all my knitting gear in when I 'm off on my knitting holiday .... In  this rainy weather all you can do is stay inside and sew.....
