Nautical Knot Baby Hat

I have been quite a busy bee recently trying to stock up the shop ready for autumn and here is one of the new designs.  I have done knot hats before but with a much thinner smaller knot but am loving this chunky one and the navy and linen colour scheme.  Now I'm trying to decide what other combinations to do, wondering about red and cream and a brighter blue and cream or linen?  Would welcome any suggestions as to colour combinations you think might look good!
