Making a onesie – romper – all in one from a shirt!

My name is Tracy I’m fellow editor to cavernofcraftiness blog and I have 2 children Big Critter (age 5) and Baby Critter ( age 3 months) both boys 🙂
I started sewing about 6 years ago and largely self taught myself before attending a few college courses. I make a lot of items which I sell on facebook but decided to set about making a large part of Baby Critters wardrobe and Big Critters dress up.
Trying to be frugal I saw a tutorial on making a shirt into a baby romper/onesie but found the pattern to be slightly lacking so here’s my version 😀
First Step
You will need:
Paper (I use lining paper)
Rubber/Eraser (just in case)
Footless babygro/romper or similar that fits
Shorts (if wish to do a shorter one)
I will be making a long sleeved full leg onesie & a short sleeved short leg version too.
Second Step
Lay your paper flat on a table. Fold your romper in half make sure outer edges & leg edges match so perfectly symmetrical or your pattern wont work. You need to do it at least 3 cm in from edge of paper. DO NOT trace this onto edge of paper like I did to start!!
Trace round this starting at armpit ending to outer shoulder. Photo below is maybe not massively clear but shows what you should end up with. Remember I did it at edge to start which is wrong. Mark bottom line with a big CF this stands for centre front.
To left of picture it shows 2 darker curved lines these are your neck lines the top is back & lower is front. To trace front keep romper on paper & just fold it the back under slightly so your able to then trace the front neck.
Next you need to draw in arm hole curve. Take the sleeve and pin it back along seam so reveals curve of arm when pinned.
Match up armpit & shoulder to pattern and finish the pattern off by tracing the curve of sleeve.
Third Step
Now you need to straighten the lines of pattern all but the neck & arm hole are straight. You then need to make 1cm from edge of pattern at outer edge (top of pattern if laid like mine) at neck & arm hole. Then 2cm at inner edge (CF), inside leg & at base of legs.
This is why you shouldn’t trace pattern at edge of paper. You will end up with a bordered pattern. The ‘border’ is your seam allowance.
Ensure you also mark 1cm for front neck line. Then mark where you want the opening of your shirt to end as this romper will have opening at front to about breast bone or where ever you wish. I marked 13cm from front neckline border.
Fourth Step
We will do sleeve pattern now.
Lay your sleeve flat on the paper and trace round shoulder to armpit.
Now we need the curve where the sleeve is sewn to the armhole of main section. As can see in picture above where armhole was curved in the sleeve curve goes out. The easiest way to do this is to draw a slight curve freehand as shown below.
Now like you did with other section add 1cm to all edges apart from cuffs add 2cm. Again this ‘border’ is your seam allowance. You should have both patterns as shown.
If you wish to do short version then follow next step otherwise skip to sixth step.
Fifth Step
Using the pair of shorts fold in half symetrically like you did for the romper. Matching the crotch of trousers to your pattern crotch mark where the hem is.
Arrow shows shorts crotch & line is pattern crotch.
using line just draw add 2cm for seam allowance. Rub out first line.
Sixth Step
We will be drawing back of the pattern now. You can either pre fold your paper or do as I do and fold after.
Fold the 2cm seam allowance on the CF edge & inside leg in you wont need this.
Lay the romper pattern towards edge of paper with the CF edge towards middle of the paper & draw round. Fold at CF and cut around both pieces from top of neck right round to crotch. DO NOT cut along CF. You should end up with one big piece. This is the back of your pattern.
You now have a back, half a front & a sleeve. You can cut the back section of the neck off the front pattern piece as pic shows so the front piece has front neckline which is lower and back piece has the back neckline which is higher 🙂


Last Step
We will need facings this means you don’t hem the neck line which makes it tidier.
To make these fold your back piece in half lay on a fresh piece of paper & trace round starting 10cm from armpit round to other side.
Do same for front. Clearly mark each piece.
Next time we will cut the romper out from our shirt & sew it up.
For this you will need:
Old shirt (bigger the better)
Your pattern
Popper tape
Bias binding that coordinates with your shirt
See you then!!

    my tips for writing are be yourself pick a topic that interests you! thats the key or you end up with not a lot to say. this blog is good ive used blogspot which is a bit simplier but wordpress is a bit easier for example can upload pictures in advance to use in blogs but blogspot you have to upload 1 by 1 as you need them & have to reload if use them in a different post hope that helps tracy

  8. Superb blog! Do you have any tips and hints for aspiring writers? I’m planning to start my own site soon but I’m a little lost on everything. Would you recommend starting with a free platform like WordPress or go for a paid option? There are so many choices out there that I’m completely confused .. Any suggestions? Thank you!

    • Hi Ruben
      Thank you for popping over! I’m a rookie as far as writing goes so I’m not sure I have any tips for you there other than be yourself! But maybe the other ladies here could offer their wisdom?! I would definitely recommend starting out with WordPress (although I haven’t tried any other sites!!) as it is really easy to set up and customise the way you like it. I would also suggest trying the free version first whilst you trial it and upgrade later if you’re happy with the site and would make use of the features included with that upgrade. I hope that you enjoy creating your own blog, be sure to send us a link when you are up and running! Best of luck Ruben. Regards, Sammy 🙂
