How to make a kids car seat organizer

Measure car seat and work out what kind of pockets you want

Measure up with at least 1 cm extra on all sides for hemming

Check those measurements again

Flip top over 10 cm and pin right sides together

Mark 10 cm in from top and on each side

You're going to cut the corners off

And sew...

Turn right side up

Fold over sides and iron, ready to sew seams on each side top to bottom

Pin and sew

Now for pockets... Cut strips longer than your width, and add facing to top of each. These will be the top of your pockets.

Lay them out and plan where they need to go

Bottom pocket... Fold over sides as shown to give some extra space in the pocket

Sew elastic just under facing to help keep pocket tip tight

Pin top pocket, allowing "bulge" space to accommodate water bottles or pencil cases

Sew in bottom pocket

Add goodies... And Voila! Hers!

His!

Don't forget buttonholes to attach to top of car seat, or straps if that's easier

And elastic sewn to bottom corner of organizer... You'll pull this around the front of the seat and pin to other corner of your organizer to pull it taut.
