OK, sorry for the wait, pc still not built but I'm not gonna let a little thing like no computer stop me!! ...well I suppose technically that isn't true but I'm sure you get what I mean

Anyway, on to the pattern!
Thanks to tigressmellora's efforts (thanks for helping out tigress!), I know that this image isn't gonna come out too good at such a low res. So...I had a think and I came up with these... not exactly what you requested but see what you think!
110w x 170h, 5270 stitches, 17 colours.
@18 ct = 31.04 x 47.97 cm
@14 ct = 39.91 x 61.68 cm
110w x 161h, 4742 stitches, 20 colours.
@18 ct = 31.04 x 45.43 cm
@14 ct = 39.91 x 58.42 cm
As you can see, I split the image in to two, cos I thought I could get a better result that way. I think they'd look not bad as a pair

I know they won't fit in A4 frames, but I'm sure there are frames they will fit in, I forget the sizes of the large frames but I do have some in my house so I know they're out there! I'd also recommend doing these in 18ct aida if you can, it may give a better result to the finished article

Anyway, let me know what you think of this idea, and if I can give any more help please don't hesitate to ask! ^^
