Unicef is calling all crafty folks to knit or crochet a square as part of a campaign to help prevent pregnant mothers from passing HIV on to their children. Sign the petition and help knit a giant baby blanket! Unite for Mothers this Mother’s Day and give a mother the chance to see her child grow up healthy… the best gift a mother could have. Unicef is aiming for 1,400 squares by Friday 1 May, which is flippin soon. So get out your needles and knit for a cause!
