Science Lab Coat Costume #1 – Mock Lab Coat (No Sew)

Birthday Party Favor Ideas line divider

 

Step: 1
Enlarge pattern to desired size.

Step: 2
Pre-wash and dry shirt; do not use fabric softener. Insert Fashion Form™ or cardboard covered with foil between layers of shirt.

What is a Fashion Form?  It is a piece of cardboard shaped in the form of a T-shirt that provides a smooth surface for T-shirt painting and prevents paint to seep through to the back of the T-shirt.  Although the Michaels website mentions this as part of their supplies list, I’d say you don’t really need this unless you will be making tons of shirts and needed something sturdy to prevent paint from seeping through.   Being the frugal person that I am, a paper grocery bag works just as well too.  Or a paper grocery bag topped with newspapers so that when one shirt is done, just replace with fresh clean newspapers.   Easy, affordable and environmentally friendly.  There, you did your good deed for the day while crafting!

Step: 3
Use a ruler and a grey chalk pencil to draw a line extending from collar toward shoulder, then down the right side of shirt as shown.

Step: 4
Use ruler and chalk to mark even spacing for buttons next to line as shown.

Step: 5
Cut out Mock Pocket Template and place where desired underneath shirt so pattern shows through.

Step: 6
Trace pocket with Black Slick Tulip 3D Fashion Paint. (Tip: Begin paint flow in the upper left corner and work down to the lower right to avoid smearing the paint with your hand.) Trace “lab coat” line with Black Slick.  Here you can change the names to whoever is on your guest list for a custom lab coat for each kid.  Kids get a kick out of this! Let dry completely.

Step: 7
Squeeze a pea-sized dot of Silver Metallics onto each button marking then carefully set each button into paint and press lightly into place. Use additional paint to connect the paint that pushes up through the buttonholes to resemble thread.  It will look like you have “stitched” the button in place, but it’s actually glued with the paint.  Let dry.

Step: 8
Pour a puddle of Platinum Metallic Soft Fabric Paint onto a piece of foil. Use paintbrush to create Platinum shading for all details as shown. Let dry.

Your Mock Lab Coat is now done!

Science Lab Coat Costume #2 – Open Lab Coat (No Sew)

  • T-Shirts (1 each): White, Blue (For the white shirt, the larger the better so that it looks like a loose lab coat.  For the blue shirt, get a shirt that is the right size)
  • Felt: White (36-inch x 36-inch package)
  • Felt Square: Red
  • Black Fabric Marker or Sharpie
  • Straight Pins
  • Scissors
  • Ruler
  • Hot Glue Gun

Note: This tutorial originally required sewing but has been adapted and simplified to a “No Sew” project using the hot glue gun by me.

Step: 1
Cut white shirt up center to separate.

Step: 2
From white felt, cut two 4-inch x 6-inch pieces.  This will become the two pockets for the lab coat.

Step: 3
Place a piece of cardboard (or paper grocery bag) inside the shirt to prevent the glue or paint from going through to the back side of the t-shirt.  Glue the 4-inch x 6-inch white felt pieces, on all three sides of the pocket using your hot glue gun.  Do not glue the top.

Step: 4
Glue the pockets to each side of the white t-shirt, remembering to leave tops open.

Step: 5
Measure the neckline length and cut a piece of white felt that length and 4-inches deep for the collar.  For example, if the neckline is 20″, cut a piece of felt the size 20″ x 4″.  This is your collar.

Step: 6
Mark the center of this collar with chalk and line it up with the center back of the neckline.  Pin the two pieces together in place as if you would be sewing them together, right sides together and allowing for seam allowance.  Instead, you will be using the hot glue gun to glue them in place.  Now glue the collar piece to the neckline of the white t-shirt, along the entire collar.

Step: 7
Use black marker to make buttons down front of shirt, or you can actually use real buttons like the previous tutorial above with 3D Fashion paint to create mock stitch lines on the buttons.

Step: 8
Cut bow tie pieces from red felt, layer together and wrap with felt to secure and glue in place.  Let dry.  Pin the bow tie to top center of the blue t-shirt with a safety pin.  This way when the party or Halloween is over, you can still use the blue t-shirt.

Science Favor Bag or Treat Bag (No Sew)

Step: 1
Print out sheets of Hazard Radio Active Symbol Template on sturdy white paper.  Cut out.

Step: 2
Cut out circles of the same size out of black felt.

Step: 3
Place one hazard symbol on the felt and glue in place.  You will now have a hazard symbol patch with a felt backing.  If  kids are part of a Boys Scout or Girls Scout troop this could also serve as their patch after the party!

Step: 4
Glue the hazard radio active symbol to the bag.

Fill with birthday party favors and test tube treats or use as a Halloween trick or treat bag.
