I love creating these memory boxes for that special occasion and have a tutorial for these on my blog under tutorial Pretty little box if you would like to look.
I use lots of puches and also my beloved spellbinders to decorate the lid and sides
This one is made from 3 sheets of A4 card and measures 9 x9 cm
I also make bigger boxes but use my Pazzles Inspiration and 12 by 12 card
