Q. What should I use instead of the tiles spacer?

Answer

Not only is tiling without spacers really tough but it's also laborious and time-consuming. It is necessary to often pause the game and readjust the tiles in order to get an equal arrangement. On the other side if you use a tile spacer you won't have to stress as much about the width and correctness of your lines. This will save you time. However while laying tile you should still use pennies as spacers rather than plastic ones that you buy from the shop. Pennies are simpler to handle more consistent and less expensive than other coin denominations.
