​TESTIMONIAL OF THE AVID QUILTER WHO INSPIRED QUILTSANDWICH— 

I have made many quilts, relying on patterns and kits.  But I have always dreamed about making my own designs....looking at my books of block patterns and dreaming up some layout that had never been done before.....cutting out each piece and stitching them together into a design of my own making.   What stopped me?  The books that contained just block designs never told me how much fabric to buy or how to figure it out.  I did buy the standard books of charts, but honestly, I didn't know how to use them.    

But now I do make quilts of my own design.  Working with my brother-in-law, who is an iOS app developer, we came up with QuiltSandwich. Because of QuiltSandwich, I can pick out blocks from my books, draw my layout and within 30 minutes of completing my drawing, I have my cutting instructions. I can use cutting and sewing techniques that I want to use, not the ones the pattern designer used, so I have better accuracy in my sewing. ​ 

​
​
And when I make a cutting mistake, (unfortunately, the app doesn't prevent cutting mistakes!)  I can recover and use fabrics I have on hand to fix my mistake.  I don't have to rely on a particular fabric line or technique for my quilt that someone else chose.  QuiltSandwich has opened up a whole new world to me.  One that before now, I could only dream about.
