Talk with the friend who took you there. Ask her if it's always like that. Quiet, contemplative, etc. If she says yes, then you have your answer.
Try to find an embroidery guild. The elderly (over 75) ladies at our church have an altar and rosary society. (I don't belong and probably wouldn't join.) You may contact one of the ladies, usually the president, and ask her where the embroidery group meets.
Perhaps post a note at the library? That's all I can think of at the moment.
