Oh My Glob! What time is it? Lumpy Space Princess Plush Making Time!!

Step 1: Creating the Pattern

Supplies Needed:


  • Computer
  • Printer
  • Scissors / Paper Trimmer


  • Tape

To create the pattern I started out by searching for some images of LSP. I wasn't finding much online that I liked so I ended up taking a few screen shots of her from actual episodes. I used 3 different pictures to create the pattern, one for the body shape, one for the face, and one for the arms. You could also draw this yourself but I wanted it to look like the real thing.

I traced out the shapes in illustrator and sized them so she would be about 17" tall, I wanted her to be pretty big but not giant ; ) After I had the pieces drawn I added a 3/8" seam allowance to the body and the arms.

From here I tiled out the pattern to be printed on 8 1/2" x 11" pieces of paper, there are 9 total and I have included the pattern which you can print and use too : )

The next step is to print out the pattern, and tape all of the pieces together. The pages are marked with registration marks so they are easy to put together. I like to use packing tape to make the pattern more sturdy. I also cut out the slits for the armholes, the finger lines on the hand as well as the gaps between the bottom 3 lumps so I could mark these on my fabric pieces.

Then you just want to cut all of the pattern pieces out and you are ready to start cutting out your fabric pieces!



Supplies Needed: 

  • Scissors
  • Weighted object (this helps to hold the pattern in place, I just used a stapler)
  • Pen/marker to trace the pattern pieces to the fabric (I used a black sharpie, and a metallic pen for the black pieces)


  • 1/2 yard of purple fabric for the body and arms. I actually used a blanket I found at target, you can find the same one here. This was thicker than the plush fabric they have at Joann's Fabric Store and a nice color too. The twin size measures 66" x 90" which comes out to a little under 3 yards of fabric.
  • 1/4 yard of yellow fabric for the star, I used a yellow satin which had glitter too : )
  • 1/4 yard of interfacing ( I like Pellon 809 Decor Bond)
  • 1 sheet of black felt for the eyes
  • 1 sheet of white felt for the teeth
  • 1 sheet of light purple felt for the tongue
  • 1 sheet of dark purple felt for the mouth

To create your fabric pieces you just need to transfer your pattern pieces onto your fabric. The pattern pieces indicate how many to cut of each and if any need to be flipped over for the opposite side.

For the star, I cut out a 4" x 4" square of the yellow fabric, which was big enough to fit the star pattern piece inside of. Then I cut out a 3 3/4" x 3 3/4" square of interfacing, I always make the interfacing slightly smaller than what I am ironing it to, so the edges don't over extend and get glue on anything. I ironed on the interfacing to the wrong side of the yellow fabric and once attached I cut out my star piece. This was easier than cutting the star shapes first and then trying to match them up, and it also created clean edges once cut.

For the body, I cut the two slits for the arm holes on the front body piece only, you won't need this on the back body piece.I also marked 2 lines in between the bottom three lumps which I used as a guide to define their shape while sewing.

Step 3: Sew The Face

Supplies Needed: 

  • Sewing Machine
  • Scissors
  • Pins
  • Body Pattern piece (to reference for face placement)


  • Front Body Piece
  • 1 Yellow Star piece
  • 2 Black Eye pieces
  • 1 Mouth piece
  • 1 Tongue piece
  • 1 Teeth piece
  • Matching thread ( I needed light purple, dark purple, black, white and yellow)

To sew the face I started by attaching the star to the front body piece. I made a fold on my body pattern piece at the bottom of the star and used this as a guide for positioning the star.

Once the star is positioned you can pin it in place and sew it to the body using a straight stitch and sewing as close to the edge as possible. I also added a thick border around the star, since I used a satin fabric I wanted to make sure that the edges didn't fray. I created this finish by using a zig zag stitch on my sewing machine and using the lowest stitch length available. To make the stitching even tighter I just pulled on my fabric as I was sewing it to give it some resistance and the stitches came out really tight and created a thick border. You could also use an embroidery machine for this but I don't have one......yet : )

Next I added the mouth, I created another fold on my body pattern piece at the bottom of the mouth and used this as a reference for placement. Then I pinned that in place and sewed it to the body using a straight stitch and sewing as close to the edge as possible.

Once the mouth piece is in place you can add the teeth and the tongue.I just eyeballed their positioning since the pieces should line up with the edges of the mouth. Pin them in place and sew them to the mouth using matching thread and a straight stitch, sewing as close to the edge as possible.

To finish the face you just need to add the eyes, I created another fold on the body pattern at the bottom of the eyes and used this as a guide for placement. Pin the eyes in place and sew them to the body using a straight stitch and sewing as close to the edge as possible.

Notes On The Face:

For the felt pieces you do not need to do any extra finishing to the edges since felt does not fray they do not need any finishing. Although you definitely can if you like the way it looks : )

Step 4: Sew The Arms

Supplies Needed: 

  • Sewing Machine
  • Scissors
  • Pins
  • Tailors Chalk (to mark finger stitching)
  • Arm Pattern piece (to reference for face placement)


  • 4 Arm Pieces
  • Purple Thread

To create the arms take the front and back of either the left or right arm and pin them with the right sides together, leaving the armhole open.

Sew them together using a 3/8" seam allowance. I also added a zig zag stitch around the seam allowance for extra protection.

Remove the pins and turn the arm right side out.

Add the finger stitching lines to the hand, I used my arm pattern as a reference for the finger stitching and marked the lines using tailors chalk since this was on the correct side of the fabric.

Sew the finger lines using a straight stitch, It is a little hard to see this in the pictures but it gives the hands some more character and shows up more when you add the stuffing.

Repeat these steps for the opposite arm.

Step 5: Sew The Front & Back Body

Supplies Needed: 

  • Sewing Machine
  • Scissors
  • Pins


  • Front and Back Body Pieces
  • Purple Thread

Pin the front and back body pieces with the right sides together, leave a gap big enough to turn the plush right side out. I positioned mine on the bottom right lump.

Sew the pieces together using a 3/8" seam allowance making sure to leave the gap open. For the 3 small lumps at the bottom I sewed the seam allowance up to a point where I had drawn on lines as a guide, this helped to define their shape. I also added a zig zag stitch to the seam allowance for extra protection.

Turn the body right side out.

Step 6: Add The Stuffing

Supplies Needed: 

  • Needle
  • Skewer
  • Scissors


  • 32 oz bag of stuffing ( you will some left over but a 12 oz bag will not be enough)
  • Purple Thread

Add the stuffing. I started by filling in the fingers on the arms, this is a tight squeeze so I used the skewer that came in my bag of stuffing.

Continue adding stuffing until you get your desired lumpiness : ) If want the arms to be able to move around freely, just leave a little gap around the armhole, this way they won't stick straight out like Frankenstein.

To finish of the LSP plush you just need to hand sew the stuffing gap closed. When I was about 3/4 of the way finished sewing the gap closed, I added the rest of the stuffing for this last lump and once it was filled I sewed the gap closed.

And your done!
