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 [Team GB] 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 yet a Canadian citizen, Schafer played for Saskatchewan at the
2014 and
2020 Canadian Mixed Curling Championship. After becoming a citizen, she was able to compete in provincial playdowns, and joined the
Robyn Silvernagle rink for the
2022–23 season with the team's goal being to represent Saskatchewan at the
2023 Scotties Tournament of Hearts. They entered the last chance qualifier for the provincial championship only having had one practice as a team. After losing their first game, they rattled off five straight victories to qualify for
2023 Saskatchewan Scotties Tournament of Hearts in
Estevan. There, they continued to build momentum with wins over many higher ranked teams to qualify for the playoffs through the B side. After dropping the 1 vs. 2 game to
Nancy Martin, Team Silvernagle bounced back to beat
Sherry Anderson in the semifinal to qualify for the provincial final. Facing Team Martin once again, Team Silvernagle took the lead in the second end and never trailed en route to an 8–4 victory and the 2023 Saskatchewan provincial championship title. This qualified Schafer for her first Scotties which was held in
Kamloops,
British Columbia. The team struggled at the national championship, finishing 2–6 through the round robin with wins over Alberta's
Kayla Skrlik and Nunavut's
Brigitte MacPhail. Schafer won her first Canadian national championship at the
2023 Canadian Mixed Curling Championship on home ice in Swift Current, playing third for
Shaun Meachem. The team represented Canada at the
2024 World Mixed Curling Championship which was a homecoming affair for Schafer, as it was played in Scotland. There, the team went undefeated before being upset in the round of 16 to the Netherlands. == Personal life ==
