Plastic Canvas Size 7 Count - One sheet of 10' x 13' should be fine.
Yarn in the colors of your choosing - I used Pale Yellow and a green I got from a garage sale.
Plastic Canvas Needles size 7 - to match the canvas.
Scissors - to cut the yarn and canvas.
Floral wire or something stiff you can use for the stem - I used 18 gauge cloth covered floral wire because it wasn't as skinny as some others.
Wire Cutters - Since it is hard to cut the floral wire with just the scissors.
I had been searching for more plastic canvas projects after having found, and creating, a Nintendo DS case that looked like an old, traditional nintendo controller. I wanted to find out how to make 3D flowers for a long time, but could never find any. I always found old, old books that showed you how to do it. I have attempted a rose, but need to prefect that, and have made plans for a tulip and daisy. For now, I present to you, the Plastic Canvas Yarn Daffodil.
Step 1: Cutting
You need six leaves. My graph paper picture shows the overall size of it and also shows what to trim off. It is 13 squares by 11 squares.
There is one center piece. It is 20 squares by 8 squares.
There. You are already doing great.
