Start by making the pencil sandwiches.  I used a slice of cheddar cheese to fill these, but you could use any filling of your choice.   Make up your sandwich, then cut off the crusts to make to straight sides as shown in the photo below.  Cut the sandwich vertically to make two long equal sized pieces.

Cut the top of each sandwich to a point, trimming the top crusts off as you do so.  Take one your sandwiches and rest the pointy end on top of the remaining slice of cheese.  Using the sandwich as a guide, cut a triangle from the cheese.  This will become the point of the 'pencil'.

Using a mini circle cutter (or the 'O' from your alphabet set), cut semicircles from the bottom of the cheese triangle as shown in the photo below. Place the cheese triangle on top the sandwich and repeat with the second sandwich to make two pencils.

Finish each sandwich off with a small triangle of cucumber skin to make the pencil leads. You can stick the cheese and cucumber skin to the sandwich with a dab of cream cheese or mayo if you wish, which will help to hold them in place whilst the lunch is transported.

Carefully pack the pencil sandwiches in a sandwich box.  I used this sandwich box from Sistema.

Next create the alphabet cucumber slices.  I made the first few letters of the alphabet, but you also could pick out the letters of your child's name, initials or class name instead if preferred.

To make, first cut your cucumber into fairly thick slices. Take your carrot, and cut slices to roughly the same thickness as the cucumber.

Using your mini alphabet cutters, cut a letter from the centre of each cucumber slice and remove the letter shaped cucumber flesh. Cut corresponding letters from each carrot slice, then slot them into the letter shaped holes in the cucumber as shown in the photos below.

Pack your cucumber slices in a mini snack container.  I love these sturdy little snack pots from Sistema that I used for this lunch.  They're great because they can hold liquids like yoghurt as well as other foods.

Pack the grapes and blueberries in another container, and mix the dried fruit and seeds together in another to make a simple trail mix.  Top with crayon cupcake picks to decorate and finish off the school themed lunch.
