"Seams Legit" June 2019: sewing a sundress!

It’s June, it’s heating up, and the studio is staying cool! We had a lovely time sewing up a t-shirt in June; this month we are stepping up and making ourselves a light sundress!

A reminder that for all sew-alongs in my Seams Legit series you need:

1. a machine with its manual; the machine needs to be tuned-up and sewing a balanced zig-zag

2. the supplies listed in the pattern, as well as a thorough read-through of the pattern you use

I demonstrate all my cutting with rotary and mat. You will need your fabrics pre-washed, and your fabric pieces cut by Friday the 28th at noon PST. In addition, you will want to do your homework: prepping your paper pattern pieces, pre-treating and cutting out your fabrics. I will demonstrate how to do this at the end of this post.

So! Let’s talk about this month’s project!


Rotary cutter and mat

Sewing machine with balanced zig zag; sewing machine manual


Thread and machine needle: universal or sharp

light woven fabric (lawn, voile, batiste or gauze)

Invisible zipper

Non-stretch interfacing (1/8 yard)

As I mentioned at the beginning of the year, each project gets successively more complex. For this sundress, you will need to do the following:

1. read through this post, & purchase your pattern & supplies;

2. create facings, pre-treat fabrics & cut your pieces (video here);

3. sew with us live on the 28th (on
my FB page or my Twitch stream):

For our pattern, we will be using a simple sleeveless dress pattern by Bootstrap fashion, featuring double box pleats at the skirt waist and very pretty chevron pleats in the fitted bodice. You can find the pattern here.

Like all Bootstrap, Tailornova, and Lekala patterns, you get to insert your own measurements and body proportions. This pattern therefore has a large size range:

waist: 17″ to 67″
hip: 17″ to 68″

We will be making a few changes: creating our own facings, adding pockets, and inserting a center back invisible zipper (instead of a side zip).

You can either buy extra yardage, or print and cut the pattern out to determine your yardage (make sure you account for the facings we will be adding).

For this pattern, you first need to create your Bootstrap account if you haven’t already (I have a walk-through on this previous post). Then, you need to find the pattern, and take the following measurements to enter into the pattern generator:

Upper arm
Low hip

Belly protuberance

Each of these measurements has a little red asterisk (*) next to the input window, so you can see a helpful diagram of exactly how to take the measurement.

You may notice there are other measurements you can take; like the “Hips + Belly (Optional)”. Ignore these for now. Do make sure to select your seam allowance, and the PRINT option at 36″, to send to a copy shop (I use pdfplotting.com).

If you have any questions, please don’t hesitate to ask them!

Please take your time making sure you have the exact measurements you need, and they are entered correctly. Make sure also, you have seam allowance selected and the correct PRINT format (36″).

This project takes more time to set up, than to actually sew. So do yourself a favor and get your pattern printed soon, calculate the yardage needed, buy your fabrics and notions, create your facings, and prepare for our sewing date on the 28th!
