Schafer made her international curling debut competing at the 1999 World Junior Championships, representing Scotland and the Letham Grange Ice Rink. With Schafer leading the team as skip, they finished a respectable fifth position. Schafer was skip for Team Scotland at the World Juniors two more times, in 2001 and 2002. Both years the team again finished fifth. Scotland's curling dominance over the two other host nations of Great Britain secured its place at the 2006 Winter Olympics in Turin, Italy. Schafer was shortlisted along with nine other female curlers to be considered for a place on the women's Olympic team and became successful to travel to Turin to defend Rhona Martin's Olympic gold that Team GB won in Salt Lake City in 2002. She joined Rhona Martin, Lynn Cameron, Jackie Lockhart and Debbie Knox. As in her other international games, Shaefer played second throughout the Olympic competition. However, despite beating U.S. 10–4 after only six ends, Team GB's Olympic hopes were shattered as Canada beat Denmark in a nail-biting match in the final end. A win over Canada by Denmark would have enabled Great Britain to go into a playoff to compete for the last semi-final position. When interviewed after the game Kelly conceded Team GB's loss was "gutting" but added "we have to take the positives out of this." Schafer won her first medal at an international event at the 2007 World Women's Curling Championship. She skipped Scotland with teammates Jackie Lockhart, Lorna Vevers, Lindsay Wood and Karen Addison. Scotland won the bronze medal by losing in the semi-final to Denmark, skipped by Angelina Jensen. Schafer returned to the Olympics in 2010, again playing second but this time for skip Eve Muirhead. Team Great Britain finished 7th with a record of 3-6. A month after the Olympics Schafer again played with Muirhead, this time as third at the 2010 World Championships. Team Scotland played Germany in the final, settling for the silver medal after giving up two points in an extra end. Though she no longer lives in Scotland, Schafer has been a frequent alternate for Team Scotland, including at the 2012 World Championships in Lethbridge, Alberta, the 2017 World Championships in Beijing, China, and for Great Britain in the 2018 Winter Olympics. Although not a Canadian citizen, Schafer played for Saskatchewan at the 2014 and 2020 Canadian Mixed Curling Championship.
