  • Aleene’s Insta-Fuse Fabric Fusion
  • 1 ½ - 3 yards of white fabric
  • Fabric in rainbow colors
  • Blue fabric
  • Iron + ironing board
  • 10” foam disc

  • Step 1 Cut clouds and straps from fabric

    Step 1 Cut out the clouds and straps

    To start this Halloween DIY, measure your body and cut out the clouds from fabric. Cut the width of your white fabric in half so that you have 2 long strips, then fold each piece in half width wise. You will use one long folded piece for the front and one for the back.

    Measure and cut the over-the-shoulder straps and some tie straps for the side of the body. For this kids’ costume, Oh Yay Studio cut 2 of the shoulder straps about 15” and 4 of the side straps about 8” long.


    Step 2 Glue cloud together with Insta-Fuse Fabric Fusion

    Step 2 Glue cloud together

    Glue your Halloween DIY costume together with Aleenes Insta-Fuse Fabric Fusion! Begin by running a bead of glue along the outer edge of the cloud. To activate the adhesive, set your iron to high and iron the glued area in circular motions for 30 seconds. Be sure to keep a close eye on your project when ironing to prevent scorching. Flip and repeat on the backside. Pull on the fabric to test the bond and repeat ironing if necessary. 

    Step 3 Alternate gluing and stuffing the clouds

    Step 3 Alternate gluing and stuffing

    Repeat ironing and gluing as you stuff the cloud with polyester fiberfill. Work from left to right and apply Insta-Fuse Fabric Fusion in semi-circles across the fabric to give your Halloween DIY fluffy, cloud-like dimension. Be sure to add the ends of both of your straps along the top of the cloud and the 2 sides straps along the sides.

    Step 4 Repeat with second cloud and attach

    Repeat steps 2 and 3 to glue and fill your second cloud. Attach the two clouds together through the top straps. 

    Step 5 Cut and prep raindrops

    Step 5 Cut and prep raindrops

    Next, make some raindrops for your Halloween DIY costume. Cut varying lengths of ribbon, then cut twice as many raindrop shapes from blue fabric. Apply Insta-Fuse Fabric Fusion and ribbon to one raindrop and place another raindrop on top. Iron to secure, then flip and repeat.

    Step 6 Attach raindrops to clouds

    Step 6 Attach raindrops

    Use Insta-Fuse Fabric Fusion to attach the raindrop strands to the inside of the rainclouds, ironing to secure into place. Attach the raindrops on both the front and back pieces to create a skirt of droplets for your Halloween DIY. This will give the illusion of raindrops falling from your cloud!

    Step 7 Prepare the rainbow template

    Step 7 Prepare the rainbow template

    This Halloween DIY wouldn't be complete without a rainbow costume headpiece! Prepare your rainbow by cutting a 10 foam circle in half. Create a template by tracing the half circle onto a piece of paper, then measure and draw 7 concentric arches onto the template. 

    Step 8 Cut rainbow colors from fabric

    Step 8 Cut rainbow colors from fabric

    Cut a strip of red fabric a 1/4 wider than the foam disc for your rainbow costume headpiece. Use your template to cut out the outer most half circle out of red fabric. Remember to cut two of every color one for the front and one for the back of the rainbow. Then cut off the first arch on the paper template and trace a slightly smaller arch onto the next color. Repeat this process with all the colors of your rainbow!  

    Step 9 Assemble the rainbow
