Patchwork or quilters help needed

[Joolly2]

I am a novice sewer and would really like to have a go at patchwork. I went to a show today and bought a packet of mini charms (2.5 inch) fabric squares with the intention of trying a patchwork technique I saw on youtube. To do it I need to source some lightweight interfacing with a 2.5 grid printed on it. I have been looking online for an hour and just can't find any. It must exist as I have watched the tutorial. Has anyone bought some or used it in the past and can tell me where to look. Many thanks.

Vilene do a one with cm lines printed on it but I've never seen one in inches. You could do it yourself by drawing on some ordinary lightweight interfacing. I use pencil but if you're worried about marking it you could use a water solvable marker.

I expect it's American - maybe try an American online quilting shop?
Alternatively you could ring up a big British one like The Cottonpatch and ask - they might be able to get it in specially for you.

I think I saw the same thing on pintrest OP, my local sewing shop sells the interfacing by the meter and I just assumed that I would need to draw the lines on myself using a yard stick/meter rule. I guess that way you can draw in different sized squares?

Thank you all for your help. I will have a go at drawing my own, but I will also try looking at some American sites, you are right about it being an American video. I didn'the notice that when I first looked at it.
