...and so on until it was slightly larger than the reels diameter (ballpoint pen for size guide).
Then a few rounds straight for depth, then some decreasing and finally a row of double crochet (UK trebles) to thread the attaching tie through.
The base was a bit more difficult to cover. Worked it in again 3 strands, 3 different shades of green to give a mottled colouring. Worked back and forth using shortrow shaping this time to create an open sided doughnut shape to make it easy to attach on. Then some details of 6 white circular spots and a little blue flower for on the base.
Picture below is most of the bits unfixed for a general idea of how it was coming along
Once I had everything done it was time for stitching. Details onto main parts 1st, and then the base. It's sewn together at the radius of the doughnut that was left open, but can easily be unstitched and re-attached should it need washed at any point. Finally a chain stich cord around the edge and pulled tight underneath. Finished result of base was pretty neat.

Next came the hard part of stuffing the seat.
With small kids about things always get spilled, so it needed to be something spashproof. Final descision was a black bag filled with chopped up carrier bags. This made it waterproof but still soft enough to be "shaped".
After much squishing and squashing and duct tape the padding was complete and the top cover popped on, again using a chain stitch cord to tie it on making it easy removed for washing.
I have to say I'm pretty chuffed with myself :-) ...
...and Wee Brian quickly picked up on what it was for.
