I think you may be referring to when Penelope tells the suitors that she will make a decision to marry one of them after she is done weaving a web of yarn. However, she was just misleading them; she untangles the work done every night for a year (I think so, that is just an estimate). However, a maid who was aware of this outs this to the suitors. When the suitors are made aware of this, they are outraged and force her to finish weaving.
Penelope
Penelope delayed choosing a husband by telling the suitors that she would choose once she finished weaving a shroud for her father-in-law, Laertes. However, each night she secretly unraveled part of the shroud, thus prolonging the task and delaying the need to make a decision.
Penelope, Odysseus's fateful wife
Penelope tells the suitors that she will choose a husband once she finishes weaving a burial shroud for her father-in-law, Laertes. Each night, she secretly unravels the shroud, delaying her decision indefinitely.
She said she would marry one of them once she had woven the shroud, but at night she unravelled part of it.
Penelope tricks the suitors by telling them she will choose a new husband once she finishes weaving a burial shroud for Laertes, but she secretly unravels the cloth every night. This delay tactic gives Odysseus time to return home and deal with the suitors himself.
She says that if they were really courting her that they would not be destroying her house, they would be getting her gifts. They all agree to this and give them to her when really she has other plans in mind for them.
Penelope was a hero for many reasons: 1) She stayed loyal to her husband. 2) She managed to trick the suitors. 3) She questioned Odysseus till the end. She was cautious and proceeded carefully. 4) She managed to raise her son alone and keep her estate.

Penelope told the suitors that she would choose a suitor once she finished weaving a shroud for her father-in-law, Laertes. However, she secretly unraveled the shroud each night to delay its completion, buying time to avoid selecting a suitor.
Penelope held a contest for the suitors: Whoever could string Odysseus' bow and fire an arrow through twelve axe handles would be able to marry her. This is a trick Odysseus did when he was younger. Only one who can accomplish the feat would be considered man enough to marry her. None of the suitors could do it except for Odysseus, who was still disguised as a beggar.
Before, she was planning to trick them by telling them she had to finish a blanket for Odyssey's father, but they found out and eventually forced her to marry one of them. It was either that or the kingdom would've been destroyed. Plus, she was lonely.
