Another tip regarding uniforms. They will get paint on them. Most schools insist on students wearing smocks during art but even this defies paint occasionally. All you can do is to hope the school uses washable paints etc. if they don't then you'll have to accept that there may be permanent stains. Don't blow your top like I did once. It's not really the child's fault. Know that by the end of the year most kids will have a stain or two... it's not worth an argument. Just something I wish I could have done better.... When my DD was in grade 5 she sustained a bright orange paint stain on the white collar of her brand new uniform that cost $85. I cracked it... instead i should have established what day is art day and make her wear her old uniform that day.

ETA: BTW my mother, who is a good sewer, managed to replace the collar the following year (the stain was on my DD's bigger uniform).
