See your amigurumi before you crochet it
From written crochet pattern to 3D model, stitch by stitch. Write your rounds the way you already write them, no new syntax to learn. The shape you see is the shape your written pattern actually describes, which is not always the one you had in mind when you wrote it.

This is the real studio, running here. Touch it and it hands over to you.
The gap between what you wrote and what it becomes
Six hours to find out
A decrease one round too early gives you a cone where you wanted a dome. Written down, both look correct. You find out after the piece is finished.
Counts that add up, shapes that don't
Your stitch maths can be perfect while the silhouette is still wrong. Numbers on a page cannot show you a proportion problem.
Expensive corrections
Fixing a line of text is free. Recrocheting the piece, reshooting the sample, and sending a revised file to everyone who bought it is not.
Three steps, no modelling
You never build a model. Your pattern is the input.
1. Write your rounds
"Rnd 4: (sc, inc) x 6 (18)". The same notation you already use, one part at a time.
2. Watch it take shape
Each round appears as you write it. Rotate the piece, zoom into the stitches, and fix the text where the shape disagrees with you.
3. Export the PDF
The pattern you checked becomes the pattern you sell, without rebuilding it in a design tool afterwards.
What you can actually inspect
Shape from your rounds
Spheres, ovals, cones, flat and rounded bases. The studio reads increases, decreases, and straight rounds and builds the silhouette they describe.
Put the pieces together
Say which piece attaches to which, and where, and see them in place on each other. Proportion is a relationship between two pieces, so it is the one thing a single piece can never show you. Sewn on or crocheted on, per piece.
Stitch by stitch
Zoom in and the surface is made of individual stitches, not a smooth skin. You can see where a round starts and where an increase lands.
Colour changes as they really fall
Amigurumi is worked in a spiral, so a colour change drifts sideways instead of landing in a straight line. The preview shows the drift, so a stripe looks the way it will look on the hook.
Eye and nose placement
Position safety eyes and a nose on the actual piece and read off exactly which round and stitch they sit on, so the instruction you write is the placement you chose.
Real measurements
Height, width, round count, and total stitches per part, derived from your yarn weight rather than guessed.
Paint straight onto the piece
Colour the piece in 3D and the studio writes those colour changes back into your rounds, already adjusted for the way a spiral shifts them.
What it does not do
It does not design for you, and it does not replace a tester. Yarn weight, tension, hook size, stuffing and finishing all change the piece in your hands, and the preview knows none of them. A tester tells you whether a real person can follow your words with their own yarn and their own tension. That is a different job, and you still need it.
What the preview does is move the structural check to the beginning, while a correction is still one line of text. By the time your testers see the pattern, they are checking your writing rather than discovering that the shape was wrong all along.
Questions about the 3D preview
How does a 3D preview of a crochet pattern work?
You write your pattern the way you already write it, round by round. Each round tells the studio how many stitches to place and whether the piece is growing, holding steady, or decreasing, and it builds the shape from that. There is no modelling and nothing to draw. The 3D view is generated from the same text you are going to sell.
Do I need to know 3D software?
No. If you can write "Rnd 4: (sc, inc) x 6 (18)" you can use it. The only input is your written pattern. Rotate, zoom, and look at the piece from any angle, but you never build the model yourself.
What can a 3D preview catch that a photo cannot?
Photos show a finished sample from one angle in one yarn. The preview shows the shape your written rounds actually describe, which is not always the shape you crocheted. A decrease placed one round too early, a straight section that should have been a taper, a piece that ends up shorter than you meant, all of it shows up before anyone follows the instructions.
Can I see the pieces assembled, not just one at a time?
Yes. Choose what attaches to what and where, and the pieces appear in place on each other, so you can judge the proportions of the whole character from your written rounds. Each piece is set as sewn on or crocheted on, since those build differently, and you can drag a piece to adjust it. What it does not do is the needle work: it shows you the placement decision, it does not sew the join.
Does it replace pattern testers?
No, and it is not meant to. A tester tells you whether a real person can follow your words with their own yarn and tension. The preview tells you whether the shape your words describe is the shape you intended. It catches structural problems early, while a fix is still one line of text rather than a reshoot and a revised file.
Does the preview account for my yarn and hook?
Yes. Pick your yarn weight and the studio derives real dimensions from your stitch counts, so a leg reads as 3 cm by 5 cm rather than an abstract shape. Change the yarn and the measurements change with it.
Can I export the pattern as a PDF?
Yes. The same pattern you previewed exports as a PDF with your rounds, your colours, and your notes, ready to list for sale. You are not rebuilding the document in another tool afterwards.
