This Union Jack bag is great for sweets for the kids whilst the box is good for small gifts, Jubilee coins etc.

For the bag:-

Cut out the gift bag with a craft knife and ruler. Pre-score the lines with something like a blunt pokey tool or dried-up biro.

This bag is just like one of the sweetie bags you get in the cinema so bear this in mind when you're assembling it.

Fold along the lines and stick it together with double-sided tape. The bag sticks together at the side and has been made so that one strip of 12mm double-sided tape fits just nicely and marks how far the bag side should be overlapped (should be clearer when you assemble it). Fold the bottom of the bag like a present before sticking with double-sided tape.

Once assembled, fold over the top twice. You can also punch holes through all the layers with a single 1/8" hole punch and thread through some ribbon to keep it closed. 

For the box:-

It's best to print onto a fairly thin card so that it folds well. You can also print the other side of the card so that the inside of your box isn't just white.

Cut out the box with a craft knife and ruler. Score the lines with an embossing tool or similar and fold along the creases completely before folding into the box. Add double-sided tape to the tabs and stick firmly into place.

Add contents and tie with narrow ivory satin ribbon.
