Easy Fleece Hat tutorial {free pattern} Monster Mash up Tutorial

1 – Cut out pattern pieces and pin

You can find instructions on how to assemble the pattern here.  The fun thing about this hat pack is that you get to “build” your own monster!  Take your time and decide on what eyes, horns, mouth (optional) you want your monster to have.  Make sure that you don’t select too pict of an eye for the size of hat you are doing.

2 – Begin to assemble and add the eyes and mouth

We’re going to do some basic and quick applique for the eyes and mouth.  First we’re going to assemble the eyes.  Layout the eyes and place the pupils where you want them. Pin – or better yet use some 505 Temporary adhesive.  Then using a zig zag stitch along the edge of the pupil, sew on. Continue to build the eye until it looks like you want it to. Then place the eyes on the right side of one of the hat pieces.  Pin. Sew on using zig zag stitch along the edge of the fabric of the eyes.  Repeat with the mouth.

Please note that for demonstration reasons I’ve used contrasting thread – but I recommend you use a thread that matched the pupil color.

3 – Sew the Horns

Sew each horn together.  For the horns a .5 inch seam.  For the “hair” use a .25 inch seam.  Sew two sides of the horn, leaving the straight side open for turning.Trim with scissors close to the top point of the horn (this will give it a nice point when turned).  Turn horn right side out, pushing the fabric so you will have a nice point at the top of your horn.Stuff each horn with a little bit of poly fill or fleece scraps, making sure that there is a finger width’s of space at the bottom with no filling.

4 – Place the ears/horns/hair and make the hat.

Place and pin the ears where you would like them to be on the hat (a third of the way down seams to work well).  You want the tops of the ears facing in, sitting on the right side of the fabric, you will then place the other half of the hat (right side down) on top.Using a 1/2 inch seam allowance, sew each side of the hat (the long curved side to the point before it dips into a “V”.  Be sure to leave the bottom (the brim) open. Now that you’ve sewn the sides of the hat it’s time to close the top.  Fold the hat in half so the seams you just sewed are touching.  Pin the “v” on each side closed.  Sew one seam along the top of the hat closing the v on both sides. (This will make a rounded top.)Turn the brim edge under 1 inch (or more/less if you like) pin and sew a zig-zag stitch over the edge of the fabric.  Snip any loose threads and turn right side out.
Tada!  Your hat is finished.Tip: Because of the layers, sew slowly over the sections with the ears – it will keep the stitches more even.



The Measurements are for the circumference of the head.  So the measurement you would get if you too a measuring tape and wrapped in around a person’s head.  Please not that fleece can have varying amounts of stretch to it.
