"What can one say about tile spacers? They are used as pegs! Very few people drop a cross at each corner (the accuracy of the tiles precludes this approach) rather the arms are used vertically to space the tile and then removed once the adhesive has gone off. 1000 in a pack is overkill; a few hundred would do. Better still an assortment of straight pegs (half a mm both sides of the main package size - in different colours to avoid mixing them) would be as useful"
