I have a nappy in butter minkee, it's quite yellow (the colour of 'I can't believe it's not Butter' ) It's a stronger colour than you'd think. I like it but I have a feeling I read on the site they have sold out of it.
How about mocha cuddlesoft? That might be nice with that embroidery too
ETA, you could also go for palest green or cream minkee. The palest green is lovely.
