What stretchers bars should I use?
First you need to decide your canvas depth i.e. how far it sticks out from the wall. If you’d prefer to have a thinner canvas, but your work is going to be over a metre long or wide, remember to order cross bars to reinforce the structure. Deep edge canvases do not really need cross bars (and aluminium reinforced bars certainly don’t!) but they can be useful for carrying purposes (remember however that they can also add to the weight of the canvas). All the art stretcher bars are already mitre cut at the ends for assembly and have slots for centre bars as well as bevelled edges, but the assembly of the aluminium bars differs from that of the professional wooden stretcher bars so be sure to read the information on their appropriate pages before purchasing.
