This bad boy I made for my front door. It's inspired by about seventeen million different wreaths pinned on Pinterest. Go search for "wreath" and you'll see what I mean. It's why I can't source just one. There isn't just one.
3 sheets green felt
1/2 sheet purple and yellow
Pretend the picture above has all green felt (I used the brown in a pinch - I only had two sheets of green)
Step 1: Cute each sheet of green felt in half (the long way). The cut each half into 1.5"ish strips (the short way)
Step 2: Glue the strips to the wreath, overlapping slightly.
Step 3: Cut the purple and yellow felt in half (long ways). Then cut each half into quarters. You should end up with 8 small rectangles for each color.
Step 4: Cut diamonds from each rectangle (fold in half twice over. Cut off the corner. Ta-da - a diamond.)
Step 5: Glue diamonds to wreath, alternating colors and overlapping tips slightly.
Step 6: Wrap the yarn at an angle in one direction (clockwise) until you get back to where you started. Tie off yarn underneath. Repeat in the opposite direction (counter-clockwise).
Step 7: Glue fall decoration over the area you like the least (like if you had to use brown felt when you ran out of green felt.)
I kind of liked the color blocking I unintentionally created with the brown felt Perhaps I'll make one for Christmas that's color blocked Christmas colors. Seems fun.
If you're hanging this outside, I'd suggest backing the wreath with a donut of cardboard or some coordinating/matching felt.
