Children and grown-ups can make their own evergreen wreath or swag with Oregon Women in Timber, create DIY ornaments and crafts inspired by the Douglas-fir, and try Doug-fir themed activities set up for all ages, then explore the museum's forest exhibits at no cost. It is a good December outing for families wanting a homemade holiday decoration, and an easy pairing with the Oregon Zoo or Hoyt Arboretum next door. Drop in any time between 10 a.m. and 4 p.m. The day belongs to the museum's 60th-anniversary Free Day Series presented by Hampton Lumber. ## Similar picks in Portland - [Gingerbread Houses / Casitas de Jengibre — Cornelius Public Library](https://grassyknees.com/portland/activities/gingerbread-houses-casitas-de-jengibre-cornelius-public-library--listing-0ea4efd546778b69949f391c) — Fri, Dec 18 · 5:30 PM – 7:30 PM · Cornelius Public Library · All ages · checked Oct 20.
