Every Sewly pattern comes with its own step-by-step sewing guide, and you can ask it questions while you sew. Type a question such as "what does staystitch mean?" or "my fabric is slippery, any tips for this step?" and an AI answers about your pattern, with its pieces and options. Each question counts as one AI message: 20 a month on the free plan, 300 on Maker and unlimited (fair use) on Atelier.
What is in your pattern's sewing guide?
The guide is written for the garment you made, with the options you chose, not for a generic version:
- the steps of that garment in sewing order, so a skirt with an elastic waist and pockets gets the casing and pocket steps, while one with a waistband gets the zip and waistband steps instead;
- the pieces list, with how many of each to cut;
- the notions, with their sizes: the zip length, the elastic length, the buttons;
- fabric quantities for 110, 140 and 150 cm (45, 55 and 60 in) wide fabric;
- cutting layouts showing where each piece goes.
The guide is on screen for everyone, on every plan. On the Maker and Atelier plans it also comes as a PDF with the printed pattern. For an overview of the whole process, from photo to printed pattern, see how Sewly works.
What can you ask?
| Kind of question | Example |
|---|---|
| A term | "What does understitch mean, and where do I do it here?" |
| A step | "How do I keep the waistband from twisting at the zip?" |
| Your fabric | "My viscose keeps shifting. Any tips for cutting and sewing it?" |
| Your tools | "I don't have a serger. How should I finish these seams?" |
| A substitution | "Can I use a regular zip instead of an invisible one?" |
| The order of steps | "Can I sew the side seams before setting in the sleeves?" |
| A mistake | "I stretched the neckline while sewing. Can I fix it?" |
| Measurements | "How do I measure my crotch depth?" |
Many questions are about words. A staystitch, for instance, is a line of regular stitching inside the seam allowance that stops a curve from stretching; an understitch joins the seam allowances to a facing so it does not roll to the outside. Whenever a word in a step is new to you, ask.
How to ask a good question
- Name the step you are on, for example "step 7, the neck facing", so the answer is about that step.
- Describe what you see, not only what you want: "the facing rolls to the outside after pressing" is easier to answer than "it looks wrong".
- Give your fabric and tools: the fabric type and weight, your machine, and whether you have a serger or a walking foot.
- Ask one thing at a time, and follow up if the answer is not clear.
- Test the answer on a scrap of your fabric before you sew the garment.
Here is the difference those details make:
| Vague question | Better question |
|---|---|
| "My zip looks bad." | "Step 9, the invisible zip: the tape ripples at the waist seam in my viscose. How do I fix it?" |
| "Help with the sleeve." | "Setting in the sleeve: I get two small pleats at the top of the cap in cotton poplin. What should I change?" |
| "Which needle?" | "I am sewing this T-shirt in cotton elastane jersey on a regular machine. Which needle and stitch for the side seams?" |
| "The hem is weird." | "The narrow hem on my circle skirt waves after stitching. Is it the fabric or my technique?" |
Check the written guide first
Some answers are already on the page and cost nothing to read: how many pieces to cut, the zip or elastic length, the fabric quantity for your width and the cutting layout. Save your AI messages for the questions the page cannot answer, such as what to do with your particular fabric or how to recover from a mistake.
How questions are counted
Each question to the guide is one AI message. So is a change to the pattern asked in words, and help with your measurements. The free plan includes 20 AI messages a month, Maker 300 and Atelier unlimited (fair use); see plans and prices. Changing options and measurements by hand never counts and is unlimited on every plan.
What the guide can and cannot do
The guide knows your pattern: the garment, its options and its pieces. It explains techniques, suggests what to do with your fabric and helps you out of a tight spot. It cannot see your seam or feel your fabric, so describe them, and treat each answer like advice from an experienced friend at the next table: sensible, but worth checking on a scrap. For your machine's settings and maintenance, its manual has the final word.
Quick fixes for problems you will meet at the machine
These come up in almost every project, whatever the pattern:
| Problem | Common cause | First thing to try |
|---|---|---|
| A nest of thread under the fabric | Upper thread not seated in the tension discs | Re-thread the machine with the presser foot up |
| Skipped stitches | Blunt or wrong needle | Fit a new needle: ballpoint for knits, microtex for fine wovens |
| Puckered seams in light fabric | Stitch too long or tension too tight | Shorten the stitch to 2 to 2.2 mm, loosen the tension a little, sew over tissue paper |
| Wavy seams in knits | Fabric stretched while sewing | Lighten the presser foot pressure, use a walking foot, let the feed dogs pull |
| A facing that rolls to the outside | Not understitched | Understitch the seam allowances to the facing |
| Notches that do not meet | Fabric shifted while cutting or sewing | Pin the notches first, then pin between them |
| Fine fabric pulled into the needle plate | Starting right at the edge | Start 1 cm (3/8 in) in from the edge, hold the thread tails, or begin on a scrap |
For threading, the bobbin and tension, see sewing machine basics.
Using the guide at your machine
Prop your phone or tablet on a stand next to the machine and read each step to the end before you sew it. Press when the guide tells you to: many "the seam looks bad" moments are solved by an iron. If you prefer paper, the PDF guide prints with the pattern on paid plans, and you can tick off the steps as you go.
