You get 1 extra per week per class after your initial 10 are done. You can also buy Universal Templates if from the Monument to Seasons Past kiosk (fortnightly limit) or for Silver from Eververse if you need more than the 1 extra class-based template per week. [quote]Updated Threader Bounty Reset: No longer resets seasonally, instead players will earn one additional threader bounty, per class, per week. New bounties available each week at weekly reset. Maximum number of available Threader Bounties, per class, is ten.[/quote]https://www.bungie.net/7/en/News/Article/destiny_update_9_7_0
