Below on the left are some willow branches I gathered. You can also use red dogwood, birch or any other type of flexible twigs. Using seagrass rope, grasses and other materials provides nice contrast.
Once you have gathered your materials the first step is twisting a wreath. This particular one is made out of red and yellow dogwood.
Once you have made your wreath base you will lay three central sticks on the wreath and tie them on with crosses. Next you begin weaving until the basket is the size you want. A trick to prevent the materials from breaking or cracking is to keep them wet. The joke about underwater basket weaving is not that far off from the perfect conditions.
Here are a couple examples made with various mixed materials. For more detailed instructions please go here and good luck!
This basket is made with red dogwood, willow, reed and moss.
This one is seagrass, grapevine, birch, sweetgrass and reed.
