Peppers is a lovely little sandwich bar in Edinburgh (near the Art College, if you’re looking for it) owned by old, old friends of mine. I’ve worked on branding projects before, but this was the first time I helped out a start-up; the first time I’d had such a blank canvas. Now, they’re very happy clients with a steadily growing customer base.The fresh-ground coffee, homemade soup and delicious sandwiches are on me…
