I've finished the boy's headboard, it's a ship on blue linen. I stuck to simple colours, simple lines and simple easy to recognise shapes for this one - I wanted it to be fanciful and dream-like without being as cartoonish as a lot of the kids motifs going around right now.
The blue linen was very pale, it should frame up well and not be overbearing when it's in place, especially as it will be quite high for a kids room (it should measure around 140cm high when it's framed up), and the colour of the thread gives you leeway to brighten up the room with other accessories.
Here is a teaser shot (taken with my phone in poor light):
I'll try to get back to the blog tomorrow with a better pic. Here is the drawing:
