Assemble Tree Units
1. Referring to Diagram 9, sew together two red print 3-1⁄2×5-1⁄2" rectangles and the brown tone-on-tone 1×3-1⁄2" strip to make trunk unit A. Press seams toward red print pieces. Trunk unit A should be 11×3-1⁄2" including seam allowances.
2. Join trunk unit A and Unit A to make Tree A (Diagram 10). Press seam toward trunk unit.
3. Aligning long edges, sew together two solid white 2×6-1⁄2" strips and the brown tone-on-tone 7⁄8×6-1⁄2" strip. Press seam toward brown strip. Referring to Diagram 11, cut pieced rectangle into a 2"-wide B trunk unit, a 1-1⁄2"-wide C trunk unit, and a 2-1⁄2"-wide D trunk unit.
4. Sew trunk units B, C, and D to bottom of foundation-pieced units B, C, and D, centering trunks under the green tree pieces (Diagram 12). Press seams toward trunk units. Trim trunk unit edges even with foundation-pieced units to make trees B, C, and D.
