Today I sent off a little mini Alice in Wonderland to school for World Book Day. I am quite proud of the make do and mend style costume (inspired by the Mary Blair designs for the Disney film rather than the original book!) The 'Alice' band is crocheted and the apron was cut and sewn from a cheap cotton pillowcase.
If you want to have a go at the hairband - simply use any DK weight yarn, make 5ch, then work 1dc in 2nd chain from hook and each chain to end. Carry on working straight in rows on these 4 double crochet until band is desired length around head, fasten two ends into a ring by working a slip stitch join.
Then work another strip in the same way of approximately 20cm long. Make two loops with this strip and sew or slip stitch join in place on top of head band. Weave in all ends and wear proudly!
