For this sample I cut a plastic bag into strips and fused them with an iron. I put the grid on some Solufleece and loosely machine stitched everything together.
This is another mesh made using the Solufleece method but laid flat instead of moulding it around a form.
Electric wire knitted on big needles:
In this sample I have built a very loose mesh by interlacing copper wire in a casual way. To create variations in colour I have briefly held the copper on a flame.
For these samples I used brass wire and knitted it on the round for a 3D result. This type of sample could also be flattened out and make a double grid perhaps with a third layer sandwiched in between or some wire or thread could be used to stitch/connect the two grids together (I am going to try this later on).
