Some people were having trouble opeing the PDF file. So I've uploaded it here. You don't need to waste money buying the stupid stencil card. The UK Yonex site has it there for you to download. Just print it out and stick it onto some card. Then cut it out with the Yonex stencil grid. Simple. http://www.yonex.co.uk/Badminton/Page.aspx?ID=189
I printed the stencil onto normal office paper, laminated it twice, and then cut it out. This gives a very sturdy and ink-resistant finish (and saved me a fiver).
I have both the downloaded stencil, and the one that I bought from MBS. You are right. The print out is quite small. You can always enlarge it in the PC, before printing but might not be of right proportions compared with the original one.
