Lissy: Here are some bedding sets that may appeal to you (hard to find a match colourwise to the stickers as they have a lot of grey):
The store in the links above does ship to Australia and our $ is almost equal to the USD at the moment so the price you see would almost be the price you pay. The shipping does cost quite a bit but if you weigh up what you want to buy (if anything) and compare costs to over here you may find it's the same, less or just slightly more. I have used the kidsline Zanzibar theme for my ds's room and I ordered a bit from the store above as the items they had weren't available in aus (even though that particular range is) including a set of wall stickers and a fleece blanket that had the same pattern as the quilt so I still had the gorgeous looking cot setup without using a quilt.
If you want custom bedding from my very quick search on etsy (etsy is like ebay but for handmade goods only) you may try contacting these 2 sellers and ask what they could do (just send the link to the wall stickers with your email) for you and at what cost:
There are some Russ soft toys out right now (toys r us have them) that have a teal colour and are quite neutral tones otherwise that may match those wall stickers you like. They are jungle animals too bar an owl. These are what they look like http://www.stuffedwithplushtoys.com/...words=jungaloo
Ive found having furry stuffies on a shelf actually collects a LOT of dust quite quickly so you're always having to wash them as babies are quite sensitive to dust (I bought large very furry animals for a shelf in my nursery as part of the matching decor).
Were you planning on just painting the wooden letters a plain colour? If you want to continue your theme of the wall stickers but cant find any bedding/decor to suit then you can have wall letters custom painted to match anything by this amazing ebay seller: http://cgi.ebay.com/7-Hand-Painted-C...item19bb24837d
If you asked she may be able to paint other MDF items for you to match (like an MDF rubbish bin, tissue box, maybe even some canvas's to go on another wall, drawer knobs for a dresser or wardrobe or even an MDF shelf with pegs for hanging coats etc on or even a picture frame to put on the shelf with a pic of your new family in it)
Here's a link to ebay for a search of Nojo's jungle babies (nojo is like a kidsline and jungle babies is thei biggest seller) so you can see what kind of custom stuff you could get if you wanted it:
Here's a link to what my nursery looked like (changed cots but you get the idea lol) - it will give you an idea of how far the wall stickers will get you in terms of wall space etc (the kidsline ones were also 5 large sheets) and what I did for a name banner and how that works etc.
