ive recently bought the grand calibur and love it! Today ive had a grand template petal box so had a little play with it.
You can just make a simple box, or use these fancy dies (included) to make patterns in the box directly or can cut them separately to be stuck on afterwards. i sellotaped them in place so they didnt move.
i then used my ultimate to score the lines.
You could line the box with contrasting card to show off the detail better.
ive added ribbon to finish the box's. they also come with matching tag die cuts too.
