Toddlermatician shirt

When I saw this fabric a year ago on a WI outing to Bee Crafty I had to have it.  Isn't this just the most awesome badass maths fabric you have EVER seen?

I love the combination of chalk-board effect with areas of mad colour.  The most awesome part about it is that the maths is correct.  It even contains reference to Napier's rules, which I even had to look up to see what they were as I've never had occasion to use them.  (Mr Button the person with the real actual Mathematics degree guessed they were to do with logarithms: they're not.)

I've only spotted one error in the maths so far (a missing factor of 2.l.b):

This will annoy me for ever.

I decided that Toddler Button needed a shirt in this epic fabric.  He likes shirts a lot now, because Daddy wears shirts.  Daddy doesn't have a shirt as loud as this one:

With every snip and stitch, this fabric seemed more awesome to me, but also more loud.  This shirt is quite... mad?  Somehow it didn't make my eyes dance when it was on the bolt, but is definitely individual as a shirt.

Can you see the patch pocket in this image?  Me neither.

The pattern is my self-drafted size 2-3 years pattern, see this previous shirt with the skewered soldiers.  Toddler has just started to wear this size in my shirts (they seem a bit bigger than commercial 2-3 stuff), so there is plenty of growing room left.  I didn't have enough patience or fabric to draft a back yoke for this shirt, so we'll have to wait until I have a longer length of fabric and less inclination to just get going fast (as a break from knitting).

Yellow buttons.

Obviously there was only one choice for the buttons.  If I intend this shirt to become a favourite of Toddler Button, it has to be his obsession colour: yellow.  He's not worn the shirt yet, but I'll be sure to let you know if it has the honour of being selected by his Lordship from his drawer in the morning.  He did want to try it on before I'd had chance to slit open the buttonholes, so I have hope.

How could I let this fabric languish in my drawer for a whole year?!  WHAT WAS I THINKING?
