18mm White Plastic Wedges (Pack of 10)

Plastic wedges are designed to slot into the inside corners of your canvas frame in order to create more tension in your stretched canvas.

Sold in packs of 10

They are particularly useful if you have found that a canvas has slackened over time & want it to be kept taut without having to re-stretch the whole canvas.

You can use either four wedges per frame or eight depending on your preference.
