I'm tempted to make one of those as well, but this is, as noted by the name, my Sigworm's ♥♥♥♥♥♥. It's always been plain grey.

I think the only thing stopping me from doing the regular one is that I've no idea how to go about the thatching.

Never seen the ♥♥♥♥♥♥ before

I like the choice of colours, looks far better than those generic yellow-ish ones you get to see oh so often :-)
