Well it could be used for any occasion but i thought the top kind of lended itself to a suprise opening instead of just the normal box/lid combo :)
I worked it out using an A4 sheet as some readers required something smaller than the 12x12 sheets scrapbookers use :)
First of all cut down a sheet of A4 paper to 10.5/8 inches.You need to measure the following and mark at both ends so that they line up on the scoreboard ready for scoring all sections.
Score all sections vertically and horizontally.
Cut out the pieces that are not needed - follow pic below for which ones to get rid of.
You can now use this as a template for use on either patterened paper or card to save doing all the measuring etc next time. Trace template onto you required paper/card.
Cut and score all folding pieces.
Use DST to secure the side reinforcements. Because this box is top opening both of the reinforcements fold into the same middle section thus making the whole box really sturdy.
Decorate as you like....i popped a little double sided velcro dot onto the lid lip which means its easily closed and opened. The stickers were found in a £1 shop and the colours are ideal for a little special pressie instead of the normal easter egg :)
