I know little big planet is quite popular (my little girl & me love it) and end part of last year a knitting magazine produced a knitting pattern by alan dart to knit your own 27cm tall sack boy. Anyway i had been trying to get hold of the pattern off ebay but they go for silly money £5plus just for the pattern so did a bit of digging and found the pattern free to download.
I know this may not be to everyones tastes but most people must have a nanna somewhere who is handy with knitting needles and believe me your kids will love it when they are the only ones with pink/blue/stripey/patterned sackboy teddies.
Hope someone out there finds this helpful as i know most of us cant afford or wont pay the silly money that the big sackboy toys sell for.
