Blue and Yellow dishcloths

The stripey cloth I started ages ago is finally finished. It is a nice size at around 8 inches square. It isn't anything fancy like I said before, but I think the colours are quite nice.
As you can see, I have also started another cloth on the diagonal in the same colours. I am not sure where I am going with the groups of cloths in the same colour, but perhaps sets are the place to go. I think three cloths in similar colours bundled together would be nice. Once blue and yellow striped, one plain blue and one plain yellow, for example. Or maybe two diagonal and one horizontal? Suggestions?
I have no idea what colours to use, though. I don't have a whole lot of solid coloured cotton left, but if these go over well, I may purchase some more. What colours are your kitchens and bathrooms (in case you wanted to use them as face/wash cloths)? Or what colours would you love to see paired together?
I am always up for suggestions for this sort of thing!
I think I may give dishcloths for birthday gifts this year. My mom can always use more, many of my friends live on their own, and my relatives always seem to love anything I make.
