My gran died earlier in the month, and has generously left my DSs £1,000 each. They are 10 and 11. I will put the money in a savings account for when they're older, but I'd like to use £100 or so of the money to buy them something they can keep forever. I don't necessarily want something that will appreciate in value - like wine or art - but rather something that they can look at as adults and remember their great-gran. Any suggestions?
