Step one: Buy cheapo outdoor table from Ikea with glass top (cost around £20).
Step Two: Paint frame using rust-proof outdoor/bicycle paint to give it that industrial mid-century look.
Step Three: Create abstract pattern by flinging white and black gloss/bathroom paint all over the underside of the glass (warning, this as we found out is VERY messy).
Step Four: Then pick a colour of choice (we chose a teal colour we had already used on lamp renovation) and once the abstract pattern has dried, paint a couple of coats on the same side to cover over the pattern, so the underside is protected from the elements.
And there you have it! We are still deciding whether to leave the rim of the table black or paint it gold to brighten it up a bit, any thoughts? Will post the results!
