How To Make DIY Barney Rubble Costume, Betty Rubble Costume & Bamm Bamm Rubble Costume Without A Pattern

Now, I will be the first to admit that I’m not the best sewer around, but I enjoy it. Last month, I set a challenge for myself, to sew our costumes for my brother-in-laws 30th birthday party. The theme was that you had to come as something beginning with the letter B and so we went as Betty, Barney and Bamm Bamm Rubble from The Flintstones.

If you know your way around a sewing machine, I’m sure you’ll be able to make costumes like this too, and there’s no need to use patterns.

Mr. G’s costume, the Barney Rubble costume, was the first one I started because to me, it was going to be the easiest. I was in such a rush because I left these to the very last minute (the night before and morning of the party) so I sort of forgot to take ‘step by step’ photos. I created a sketch for each costume to get the idea I had in my head onto paper and pretty much followed them.

I’d have to say that although the Barney Rubble Costume was the biggest, it was the easiest to make.

I didn’t use a pattern but sketched my idea out on a piece of paper. I took my husbands measurements across his shoulders, from his shoulders to the bottom of the costume and across his waist.
DIY Barney Rubble Costume



  1. Fold the fabric in half with the incorrect side facing outwards and the fold at the top, this will become the shoulders.
  2. If you haven’t been able to take measurements, get a shirt or similar and lay it on top of the fabric with the shoulders of the shirt in line with the fold.
  3. Using a piece of chalk, outline the shoulders and the arms, right down to the bottom. Don’t forget to allow for a lot of extra width as this is a very loose fit costume.
  4. Draw the triangles which will eventually be cut into a jagged hemline.
  5. After marking it out with chalk, cut it out using fabric shears and sew the side seams.
  6. Thread the cord through the eyelets to form the crossover detail on the front neck.

How to make a Bamm Bamm Flinstones Costume

Because there’s no hemming involved with these costumes, it’s pretty much a matter of sewing the material pieces together with one long stitch. The Bam Bam Flinstones costume is the only one with the elasticised waist which again, is simply a matter of sewing a straight line to form the hole in which to thread the waist elastic through. If elsastic seems too tricky, you could even use a spare piece of brown material and thread it through to make a tie.

  1. Fold the fabric in half with the incorrect side facing outwards.
  2. Draw the shape of the skirt on the fabric with the chalk.
  3. If you haven’t been able to take measurements, just use a pair of shorts and trace around them, remembering to allow a bit of extra width for the waist as this will be gathered smaller when the elastic is put in.
  4. For the brown sash, cut a straight piece of fabric in double the width.
  5. Fold the fabric inside out and stitch the seam. Turn it right side out by folding it back into itself.
  6. Sew the sash onto the front of the skirt to be worn over the opposite shoulder.
  7. Sew a little loop with the chocolate fabric at the back of the skirt so you can loop the sash through it and secure it with a safety pin.
  8. To add a little bone through the front of the sash, cut two little slits and insert a bone made of cardboard or perhaps a dog biscuit in the shape of a bone.
  9. Using the brown fabric, cut out individual triangles and sew them individually over the front and back of the bammbamm skirt.

How to make a Betty Rubble Costume

Who would have thought making a Betty Rubble costume would be so much fun! Even if you’re not a sewing pro (I’m not) but know you’re way around a machine, follow these instructions and get yourself close match dress as a template, you’ll have the finished product in no time and your Barney and Betty costumes will surely take out top prize!

Betty Rubble DIY Costume The Flintstones



  1. Fold the crepe fabric in half with the wrong side facing outwards.
  2. Make sure the stretch of the fabric is widthways/horizontal so it stretches properly when you wear it.
  3. Get a dress that is the same fit , lay it on the crepe fabric in the correct position (taking into account the location of the stretch) and trace around it with chalk.
  4. Also, trace the neckline. If you need another dress to do this, lay it in the right position and trace the neck.
  5. Chalk the triangles for the jagged hem at the bottom of the fabric.
  6. Cut out the fabric, pin both sides together (correct sides facing each other) and sew the seams together making sure you use a stretch stitch.
  7. Once seams are sewn, cut a length of black velvet fabric long enough to line the neck and become a tie up halter neck. It should be wide enough to be folded over and sewn to a width of about one inch.
  8. Cut two lengths of black velvet fabric long enough to line the dress from the underarm right up to where it meets the neck. This should be cut in the same dimensions as the above.
  9. Once the black velvet is cut, fold it over so the incorrect sides are facing out, sew the seams and pull it right side out.
  10. Sew the piece of velvet along the neckline with equal lengths on each side to form the neck tie.
  11. To finish off the arm pits, set the velvet under the arms right up to the neck piece.
  12. If the back of the dress seems a bit loose, you can sew two darts (folds)  into it to make it firmer.
  13. Finally, hand sew the white button onto the neckline.

    Now that is impressive!!! And I have to say if you’re not much of a sewer than I’d hate to think what I can call myself!! Very clever Eva – and I suppose you are very right, we can do whatever we put our mind to 🙂

    I am super impressed!! and you did all this without a pattern! The only things I’ve ever sewed are bags without zips (which a friend of mine affectionately calls pillow cases with handles 🙂 Great choices as well going as Betty, Barney and Bamm Bamm – I like the ‘family’ theme there! Gorgeous photo of your guys too.

    You are so clever! Sewing machines and I do not get along…I always seem to break them. What lovely photos for your son to look back on when he is older. Have a great week!

    I’m a sewer too! So this post was definitely interesting for me. I love reading about other people’s projects. Your Betty Rubble dress looks pretty good! Nice fit… good call using an existing dress as a guide.
