Luckily I have known plenty of Good Mothers in my life so I've learnt not to rely on my own instincts but to stop and say "what would a Good Mother do?" and then go with that. So when they asked if they could do some tie dyeing (they both learn Indonesian at school, and Ibu Fiona taught them tie-dyeing one day, strange but true) I checked my initial response "god no! what a pain" and decided that a Good Mother would facilitate this wholesome activity.
It took me an hour to set up, another hour to clean up, for just ten minutes of dyeing, but I think they had fun. The t-shirts are batching so we'll see how they turn out, and if they will ever wear them! My guess would be no. We won't be doing it again.
On a happier note, my 19 yards from Hancocks finally arrived - I'm no longer surprised by their five week delivery times. You get what you pay for, and this was free shipping. I went with neutrals and blenders for this pile, and I'm pleased with all of them! It cost me less than $90 Australian, which is such a bargain.
