Are you wanting to use one color for one and one color for the other and can't decide which one to use for each of them?

exactly

I think I would use the purple one for TTL and the yellow one for Summer Solistice.

That's a good point. I was thinking the nupps might be prettier in purple, but summer is yellow

I think I am gonna do the Summer one in this yellow yarn that I picked up yesterday.

I love your clue 1 for TTL

Thank you!
