i am sure you can get these photocopying shops in the uk ( we have them i my country) whre you just walk in, hand over a pile of papers and they bind them with a plastic or metal spiral and put a cover in as well? takes about five minutes.
I use a spiral bound diary which I bought online. They do cost four pounds each but what I do is I give the first one to a child who starts with me for no charge then I ask parents to pay for the second and consecutive ones (they last 4 months if a child attends 3 days a week). If they choose not to buy them I send an email at the end of the day with the same outline as the diary. You could have a proforma tick sheet, whereby you list the activites/crafts etc and tick them. This way you would only have to write a short paragraph/sentence at the end?
I havent found it to be a problem with the binding coming loose.
