Felt acorns are one of the easiest ways to try needle felting. You roll a little wool into a ball, firm it up with a barbed needle, and glue it into a real acorn cap from the yard. Shayda Campbell shows the whole thing in under five minutes on her YouTube channel. Her finished acorns fill a bowl on the coffee table in deep green, cranberry, cream and soft grey. They also hang on the tree.
How to make felt acorns: the short version
- Collect acorn caps and let them dry.
- Roll a tuft of wool roving into a tight ball.
- Jab it with a felting needle until it shrinks to fit the cap.
- Trim the fuzz, hot glue the ball into the cap, and you are done.
Finding and prepping acorn caps
Pick up caps on a fall walk. Oak trees drop plenty in September and October, and the caps often sit apart from the nuts. Look for whole caps with no cracks. Some still have a little stem, which is handy for tying on a hanger. Shake out any dirt, rinse them, and let them dry on a tray for a few days. A low oven (about 200F for an hour) dries them faster and kills any bugs hiding inside. No oaks nearby? Craft stores and online shops sell bags of caps.
Wool roving and needles
Roving is wool that has been cleaned, dyed and combed but not spun into yarn. That loose, fluffy texture is what lets the fibers tangle. Any color works. Natural browns and greys look like real acorns, while jewel tones look festive. A small bag of mixed colors makes dozens of acorns.
A felting needle has tiny barbs along the tip. Each jab drags fibers down and knots them together, so the ball gets smaller and firmer. A 36 or 38 gauge needle is a good all rounder for this project.
Keep your fingers safe
Felting needles are very sharp and barbed, and a poke hurts. Shayda holds the ball in her fingers, but a foam felting pad under your work is safer while you learn. Stab straight in and straight out, keep your eyes on the needle, and wear leather finger guards if you have them. Grandchildren can help pick caps and colors and do the gluing with a low temperature glue gun. Keep the needles for grown ups.
How firm is firm enough?
A finished ball feels hard when you squeeze it. It does not squish, and most of the loose fibers lie flat. Expect the ball to shrink to about a third of its starting size. Start with more wool than you think you need. It is easier to felt a ball down than to build one up.
Ways to use your felt acorns
- Pile them in a bowl with pine cones and greenery for a fall or winter centerpiece.
- Tie pairs to twine loops for Christmas tree ornaments.
- String a dozen on twine for a mantel garland.
- Tuck one into the bow of a wrapped gift or a place setting.
Common problems
- Ball too big for the cap. Keep felting. It will shrink.
- Ball too small. Wrap a thin layer of roving around it and felt it in.
- Flat sides. Turn the ball every few jabs so it stays round.
- Broken needle. You stabbed at an angle. Go straight in and out.
