Join Ikea tables together to make cheap sturdy shelving units. Pictures shown are Lack tables, costing £6 each, I have now made a shelving unit thats 4 tables high and stacks to the ceiling, saving me so much space!!

They are super solid and a much cheaper solution than alternatives, also printed in the same colour as the table you can barely see them, done one in white to show design clearly. Ive also done a set in orange as black and orange is my favorite colour scheme!
