The most unique part of Kosher Patterns is .. “My Sloper” software program which allows one to input every imaginable measurement – in order to take the Kosher Pattern designs and quickly create a custom-designed pattern specifically for the user. If one isn’t a seamstress, one could miss how vital this one-of-a-kind program is. Poor-fitting necklines, inaccurate shoulder slant, waist-length too long or too short, bust girth (along with price) and more cause women to shop for endless hours with often the same obstacle coming up over and over again – the clothes are standard sized. If one has a shorter than average neck, or a fuller bust, but narrow shoulders, for example, simply moving up one size will NOT provide a better fit. With Kosher Pattern’s My Sloper – all these challenges are eliminated. It’s no wonder many young girls and ladies find tzniut such a challenge – the choices are too limited!Rabbanit Alfasi

You make tznius look beautiful! Thank you very much!
Great workmanship!
I love the way it looks and it didn’t take long at all, many thanks!
I have been a very satisfied customer of a website called “Kosher Patterns” which is unique in two ways that are inspiring for frum women anywhere.  First, they are the ONLY English-speaking company that offers tzanuah patterns for the chareidi market and it is, as far as I know, run almost if not entirely by a chareidi woman.

What type of Web browser does My Sloper support?

Currently, we support My Sloper on Firefox; Firefox being the most accurate renderer for My Sloper. My Sloper is not supported on mobile devices.

Can My Sloper run without the Internet?

Yes, My Sloper is designed to run offline without the Internet. Although the front Terms of Usage page contains web links, they are not crucial to the operation of My Sloper.

Can I sell garments sewn from patterns generated from My Sloper?

For My Sloper version 1.72 and below, the answer is no, unless you have contracted with us through our Cottage Industry License for Home Sewing which can be purchased annually.

For My Sloper version 1.8 and up, the answer is yes, because it will have a built-in contract for selling garments from patterns generated from My Sloper.

Can I sell patterns generated from My Sloper?

Unfortunately, no. However we are working on a version of My Sloper that allows branding of your label that will allow you to sell patterns generated from My Sloper. Stay tuned for more information. Sign up for updates.

Does My Sloper support both knit and woven garments?
Absolutely, yes! Other pattern-making software out there sells separate knit and woven components, but My Sloper does not limit you to only one type of fabric. The idea behind designing for knitwear is that the sloper is usually one or two sizes smaller because the design is dependent on the elasticity of the knit fabric to expand and cover the wearer. Since we design My Sloper for modesty, we do not encourage the use of elastic knit fabric that will cling to the wearer and definitely do not encourage the user to design one or two sizes smaller for modesty sake.
What size range does My Sloper support?
While other pattern-making kits and software sell separate adult and children’s components, My Sloper supports all sizes from babies to women without any upper size limit.  It all depends on the amount of virtual memory you have on your computer.  See this article for more information. Although many of the slopers are designed for women and girls, My Sloper can be used to design for menswear using the basic blouse sloper for men’s basic shirt. My Sloper 1.8 will have support for jackets and coats, and it can be used to design men’s jackets and coats as well.
Does My Sloper Demo support printing of patterns?
Absolutely, yes! The demo version of My Sloper Blouse lets you print and test out the Basic Bodice Sloper with Basic Sleeve and Bust Darts based on your custom measurements.

If you are happy with the Basic Blouse sloper, you will most likely be happy with the other styling of the blouse, dress, vest, jackets, etc.

We also offer other demo versions for My Sloper Dress and My Sloper Collar.
