A short flick through my Ravelry faves served up Short Notice and Bug Warmer by Taiga Hilliard. These patterns are the perfect blank canvas for stripes and looked quick and simple. I wanted to use neutralish background colours with a single rainbow splashed across the chest and I think it's worked really well.
I chose little rainbow buttons because you can never have enough rainbows!
Julian vest in yellow DROPS Paris. I'd knit one of these in grey for Alice and it had been very well received. I knew that one was all washed and ready for the new baby to wear so I made this one in 3 month size for when he grows out of the grey one. I love this pattern, I've knitted it three times and I'll probably keep knitting them for any babies that cross my path, it's just adorable.
This one has slightly different rainbow buttons, but still rainbows because apparently I can't help myself (and I seem to have loads in my button tin) and I think they look super.
