A :

Please watch our free tutorial on "Deep neckline theory". The link is below: . 

Q : Hi, u said the chest line can be draw 1/2” below , if we do so do we have to make any changes in sleeves,because the arm round measurement would change after changing chest line right... - R San (6 months ago)
A :

Yes, you need to do it for sleeves too but after drafting sleeves, measure the front and back curves and see if it matches with the body pattern. 

Q : Hello mam, my armhole is too tight even though increased my armround length... Should I need to increase my chest width pls reply - Subarnalatha (8 months ago)
A :


First step towards making a well fitting garment is taking accurate body measurements. Kindly double check your measurements and also check if they are marked correctly on the pattern. 

Q : Hi savi this method works very well and I am glad i took more classes with you. I have a query please help me. WHen must the deep neck theory be applied ? What is the sequence of steps in drafting. Because the deep neck theory is a separate video this is not quite clear. How to fis drastically big armholes after deep neck theory is applied? and how to rectify the altered strap widths ? Am i missing something :( - Diya (8 months ago)
A :

Answered in your similar other query. 

Q : Hi mam, your videos are very superb, neatly explained, very easy to follow... Thanks for that - Subarnalatha (8 months ago)
A :

Thanks for your kind appreciative words.  Kindly take sometime to post a review/rating below the class. 

Q : Hello mam... I want to learn kurti pattern in detail.. how to calculate armhole and sleeves can u help me in this ? which paid tutorial i have to do then ? - Sonali (1 year ago)
A :


Armhole and sleeves drafting is shown in our free tutorials. If you have not yet watched our free classes, you may start with the FREE BEGINNERS COURSE under ONLINE CLASSES - BUNDLE DEALS. After that you may start with the Kurthis foundation course Class 1 - How to give darts in a garment. 

Q : Hi Savita, I have been trying to draft the pattern for kameez and sleeve but I am finding it difficult to fit the sleeve into the armhole because the sleeve is too big. I have adjusted the chest line but it still does not work. Please could you take a look at the images. - FARIDA DEDAT (1 year ago)
A :


Always after drafting the body pattern, measure the front and back armhole curves and see if it matches with the body armhole measurement plus ease given on chest. If less/more, shift the chest line down/up and redraw the curves. After that draw the sleeves pattern and again measure the front and back curves and see if it matches with the body pattern. If less/more, increase/reduce the ease and redraw the curves. The way you have drafted looks fine, however, you may need to increase or decrease the ease to match with the body pattern. 

Q : My armhole round is 17.5". My shoulder is 15". I am finding half armhole from shoulder slope down 8.75" is too big? Can you please correct me? - Rozmina (1 year ago)
A :

You need to apply 1/2 of your arm round measurment [biceps] not armhole.  

Q : How much does a set square costs and do you supply? - Bhuvana (1 year ago)
A :

Big set square is available in the SUPPLIES section of our website -

Smaller set squares are also part of our pattern making kit. 

Q : What is the paper used to drafting? - Bhuvana (1 year ago)
A :

It is called pattern paper. It is similar to brown book binding paper [without laminate] but longer and wider. You may buy these pattern sheets on our website under SUPPLIES section. The link is here:

However, you can also use any other paper for drafting the pattern. If the paper is not wide and long you may join two or three sheets using cello tape. 

Q : Hi, Thank you very much for your prompt response. Bust round of the Dummy is 40 Inches. - SUNNY MANGLICK (1 year ago)
A :

You are welcome. 

The arm round would be approximately 13.5" and armhole 17.5". Sleeve length is 5- 6" and sleeve open can be kept at 12.5".

Q : Hi Savi, How are you doing? Recently i have Join you Online classes and they are very interesting and easy to learn. I have a Question regarding the Chest Line marking. In your video you have explained that Chest line half of the Arm Round measurement. Now i am making a Pattern for a Kurti and i have taken the measurement of the Dummy/ Dress Form. In Dummy we don't have the Arms in it. So i dont have Arm Round measurements & Sleeves Length Opening Round with me. In this case how we will calculate and mark the Chest line? - SUNNY MANGLICK (1 year ago)
A :

Hi, thanks for your appreciative words. 

This is not a real life scenario, however please let me know the bust round of the dummy. Based on that will tell you the approximate arm round measurement. 

Q : I made this for measurements where bust size was 32. The fron neck gaped at the center by 1 inch. It could be because of the hollow chest. The neck deep was normal like 5". How could I have rectified this before hand ? You suggest taking in 3/4 inch at armroundline . Had I taken in by 1-1.5 inches would this resolve the issue ? Please let me know. - Diya (1 year ago)
A :


Are you sure the neckline isn't stretched which may be causing the gaping? If that is the reason, an easing stitch at the neckline [as shown in our free class on fixing a stretched neckline] should resolve the issue. 

3/4" is the standard we take at mid armhole which suits most women. However, if when you see the person you are making the garment for  has a shoulder more bent towards the front [which may cause a hollow chest] you may need to take some additional measurements like the front measurement from chest centre to mid armhole of one side by which you will know if you need to change the 3/4".
