......That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.
first stanza of William Wordsworth's poem that I had to learn off by heart at school... it still sticks in my mind every time I admire clouds....
Well here are your clouds, you will have to organise the daffodils... :)
A sky of fluffy clouds for you, acrylic puffy clouds, sized 22mmx14mm long, 6mm thick, sold in a packet of 20 clouds, enough to use, enough to share... :)
You can place them two ways up, so it looks like two different clouds.
I'd make sure I taped these off, or covered them with BluTac or the like before grouting, especially if you are using a dark grout, just in case some colour sticks to the acrylic. These have a flat back, so you can always glue them to your work afterwards to give extra dimension.
Don't be limited by your materials. Play with your tess-array.
