Savoury Grounds (the Kingston Rd. and Vic Park location, specifically) roast their own beans, so they have a heap of burlap bags - a score for the crafty archer. If you ask nicely they'll give you as many as you want, but you probably only want one. It'll make 4 nice size targets. You want to bring a plastic bag to put it in because it'll shed itchy stuff all over. I used printer paper that makes iron-on transfers and next time I'll use the transparent kind because it's way cheaper and some of the weave's pretty light-coloured.
I got the idea from Gary at Basically Bows, who has some nice printed ones. My brain works like this: "I like that! How can I make a difficult project out of this?" It was indeed a challenge because I begged at many cafes before I found one that did their own magic (and naturally it was the one closest to home). Of course I wanted to make a target to use the next day, so I scrambled around town searching, delaying the gratification of a London Fog till I got the goods. As it happens, Savoury Grounds get raves for their London Fogs. As it also happened, when I asked there was a lovely old gent snarfing java there, who perked right up when I asked for the sack. "Archery? Me, too!"
