Howald joined the Binia Feltscher rink at lead in 2017. She previously played with Melanie Barbezat and with this rink won the 2014 Dumfries Curling Challenge. They played in three Grand Slams in her first season with the team, qualifying in one of them, the 2017 Boost National. She got to play in her first official World Championship at the 2018 World Women's Curling Championship after being the alternate at her previous three appearances. The team struggled that week, failing to reach the playoffs after posting a 5–7 record. At the conclusion of the 2017–18 season, Irene Schori left the team and Howald was promoted to third. The team almost made it to the World Championships that season, but were bested by Silvana Tirinzoni 8–7 in the final.
