I made these coasters sets for a charity golf fund raiser. I created the holders using makercase.com. I discarded the tops and modified them in Inkscape. I designed the coasters in Inkscape using some graphics that got from freepik.com and modified using Gimp and Inkscape. One group I engraved the golfer and they took about 12 minutes each and the other group I scored the golfer and the time came down to 6 minutes each. The both sets were acceptable.
