This is how to create small or large boxes from paint samples. This can be used as anything from a DIY couples wedding ring box to small storage compartment. You can convert the measurements from centimeters to inches if you can find big enough samples! The samples are free and i got mine from Homebase.
To make the bottom box you must make a square piece of sample that is 5cm/" by 5cm/".
Next, from each corner measure across each way 1.5 cm/". (see the photo) Join up all of the marks with dotted lines, these will be your fold lines.
Then, cut a line into the inner square from one of each corners. (again, see photo!)
Finally, glue all the tabs to the inside. I used double sided sticky tape as it is neater and you can take it apart.
