Instructions

Project Note: Although this is a kid’s costume, it should only be made by an adult.

Step 1 We’ve got pattern pieces that’ll make this costume a breeze to put together! Start by Clicking on the pattern below to download and print all the templates, then cut out the individual pattern pieces.

TIP: Our tail template is larger than a single 21.6 cm x 28 cm sheet of paper, so you’ll need to print it out in tile format, then tape the tiled sheets together to reassemble the pattern. You can find the option for tiling your pattern in your printer settings. 

Step 2 Trace the spike triangles onto your sheets of Goldenrod felt. You’ll need ten large spike triangles and two each of the other five sizes.

Step 3 Now you’ll make the spike inserts that will help keep the spikes standing straight up. These are the dotted line patterns on the spike template. Cut five large spike inserts and one each of the other sizes out of stiffened felt, for a total of ten.

Step 4 Lay out five of the large Goldenrod spikes and one each of the smaller sizes of Goldenrod spikes. Place a matching stiffened felt insert in the center of each spike. Apply strips of Fabric Fuse tape to the two sides of each large spike, leaving their bottoms open. Apply strips of Fabric Fuse tape to all three sides of each smaller spike. Lay the coordinating spike on top of each, and press around the edges to fasten the spikes together.

TIP: When you’re done, the five larger spikes will have open bottoms and the five smaller spikes will be completely sealed shut.

Step 5 Next, cut a strip of blue felt that’s 6.3 cm wide and the length of the back of the T-shirt.

Step 6 Lay the T-shirt flat on your work surface with its back side facing up. Place the blue felt strip on top, running vertically down the center of the shirt. Arrange the five large spikes down the length of the strip, spacing them evenly. Spread open the bottoms of the large spikes and apply a strip of Fabric Fuse tape to the tab on each side. Attach each spike to the blue felt strip, then use more Fabric Fuse tape to fasten the blue felt strip down the back of the T-shirt.

Step 7 Let’s make the belly! Trace the large, oval belly pattern onto Cashmere Tan felt and cut it out. Trace the small circle pattern from the belly pattern onto Cashmere Tan felt 16 times and cut out all 16 circles. Use hot glue or Fabric Fuse tape to fasten each circle onto the large belly piece, overlapping the circles so they look like scales. Trim away the parts of the circles that stick out past the edge of the large belly piece, then use the tape to stick the belly onto the T-shirt’s front. Set your dinosaur shirt aside.

Step 8 Your dinosaur’s tail is next! Trace the tail pattern onto your blue felt and cut it out.

Step 9 Lay the felt tail flat on your work surface. Arrange the five smaller tail spikes so they’re evenly spaced, with their bottom edges inside one edge of the felt tail. Make sure they’re placed in descending order, with the largest spike near the tail’s fat end and the smallest near the pointed end. Fasten the spikes in place with Fabric Fuse tape, then fold up the other edge of the tail and stick it to the spikes with more tape.

Step 10 Stuff the tail with Poly-fil®.

Step 11 Cut four strips of blue felt that are each about 1.3 cm x 4 cm. Glue them along the top of the tail, between spikes, to cover up any areas where you may see the Poly-fil®.

Step 12 Now, pull the edges together at the top of the tail and secure them with Fabric Fuse tape.

Step 13 This dinosaur tail needs a waistband! Measure your child’s waist and add about 15 cm - 20 cm (just enough extra length to tie the waistband in place). Cut a band of blue felt in this length, then fasten the tail to the midpoint of this band, using hot glue or Fabric Fuse tape. Your tail is finished and you can set it aside.

Step 14 Now we’ll make spiky wristbands. Cut a piece of blue felt that’s about 10 cm x 18 cm. (You can adjust the exact length to the size of your child’s wrists.) Cut another four strips of blue felt that are 1.3 cm x 20 cm, for the wristband ties.

Step 15 Trace the cuff spike pattern twice onto Goldenrod felt and cut out both pieces.

Step 16 Attach each cuff spike to one edge of a blue wristband using Fabric Fuse tape.

Step 17 With the same tape, fasten two wristband ties under the spikes on one wristband, along the edge that’s 10 cm. Attach two more strips to the opposite edge. Repeat for the second wristband. Set your wristbands aside.

Step 18 Finally, make the giant feet! Trace the foot pattern twice onto blue foam and cut out both pieces. Hot glue each foot onto another sheet of blue foam, then cut that out, too. The double layer will give the feet more strength and stiffness.

Step 19 On each foam foot, draw an ‘X’ that’s just large enough for your child’s foot to go through, but still small enough to stay on the foot when worn over a shoe. Cut out the ‘X’ and your dinosaur’s feet are finished. What a terrifying sight!
