YARNSHAPE GUIDE
How to plan and assemble crochet pieces
A design is more than a collection of shapes. Its assembly plan explains where each piece goes, how much of its edge is sewn, and which openings remain accessible.
Arrange the design before recording a seam
Use Move piece, turn the view, and inspect the front and side. A finger, petal, or stem can overlap its neighbour in the preview without a sewing connection existing. Select the piece you intend to attach and give it a distinctive name.
Choose the two attachment points
Open Sew pieces. Choose an anchor on the selected piece, a target piece, and an anchor on the target. For example, connect a stem’s bottom to a rounded body’s top. With Snap anchors together selected, Yarnshape moves the source piece to align those points.
An anchor is a schematic location such as top, bottom, or centre. It does not identify an exact round and stitch. Snapping does not merge the pieces into a seamless crochet construction or calculate how many stitches to catch with a needle.
Write notes that can guide real assembly
Use the sewing note to describe orientation, edge coverage, and the order of work. A useful draft note might say “Centre the stem on top of the body; attach around the lower edge. Check placement from the front before securing the tail.” Once a sample exists, replace approximate placement with the actual rounds and stitch positions you used.
- Identify front and back, especially for asymmetric pieces.
- Say whether an edge is fully sewn, partly sewn, or left open.
- Record whether a piece is flat, lightly stuffed, or filled before closing.
- Leave a suitable sewing tail where the finishing instructions call for one.
Compare the edges on a sample
Two aligned points do not establish seam fit. Compare the available edges, distribute the attachment evenly, and check the shape before securing the yarn. If lengths differ substantially, revise the part sizes or the attachment plan. A broad open rim and a small target surface may require a different construction.
Follow the finishing instructions for each construction. A tube stays open at both ends; a cup has an open rim; a soft open piece is flattened and closed at its opening before attachment. A preview cannot confirm the strength or feel of these joins.
Keep the assembly plan with the pattern
Open Pattern & make to review the recorded connections alongside the separate piece instructions. Export or print the draft, and save a JSON backup so you can revise it later. Mirrors and repeated copies need their own sewing connections.
Start with a simple trial object. The amigurumi planning guide explains how to keep the first design manageable; the gauge guide explains why actual fabric dimensions matter.
