Here's a list of a few of my favorite Australian felt wool online stores to add to the mix:

Glenora wool and weaving - http://www.glenoraweaving.com.au

I've used a wide range of felt wooltops and Glenora wool and weaving are probably the best - the fibres are always super clean (which may not sound like a big deal but I have brought some wool tops still with 'bits' of grass in them, they have a range of basic to advanced colours (they pretty much have every colour in solids and a lot in mixed colours) and very easy to work with. Christine has great customer service!!

Fibre Fusion - http://www.fibrefusion.com.au Lovely range of colours from gorgeous pastels to brights. They also have really gorgeous pre-felts.

Treetop colour harmonies - http://www.treetopscolours.com.au
A fantastic colour palette like no other! Lots of great bright colours in the wooltops but also in a range of silks for nuno felting.

Fibre Dyeversity - http://www.fibredyeversity.com.au You'll be surprised looking at the website but when I was hunting high and low for a large quantity of pure pure white fine wooltop they were the ones who had it!

I love it!  - particularly the recycling aspect of re-using and bringing it back to useful life!

Got to love resists they just work so well with felt. Love your colours!!

A couple of random thoughts for you:
- she may have used a synthetic fibre which won't felt as well and sit more on top but it looks all the same colour throughout so not sure if that's what she's done
- she may add tufts towards the end of the process so that they catch a little with the underneath but don't felt right in to blend with the rest but sit more on top - try adding them almost at the end and they get felted in enough to sit but not blend??

I know you tend to use the word "refreshing" for a drink or food but that's the word I thought of when I saw your quilt: refreshing! Lovely design and colours, the little birds are super cute - Love it!!!

Sewing big buttons on felt is a good idea - did you just use an ordinary sewing needle? I tried sewing with tapestry wool in and out of holes punched into a piece of felt with my 2.5 year old but she didn't really take to it: maybe too boring??

This is a lovely idea! My daughter loves to pretend cook and this would be perfect for her.

That's beautifully fine nuno felting - well done!
