The most adaptable construction
A drawstring pouch is the most forgiving format in fabric packaging — it accommodates contents that vary slightly, it reuses established patterns, and it is the fastest construction to move into production. Where a program needs several sizes or a wide colour range, this is usually the format that makes it practical.
How a drawstring closes
A drawstring gathers the mouth of the pouch rather than sealing it. It is forgiving of contents that vary slightly in size, and it presents well as a gift because opening it is a deliberate gesture. The cost is height: the channel and the gather both need headroom above the contents, so the finished pouch is always meaningfully taller than what goes in it. Specify from the packed contents and let the clearance be added to the pattern.
Check the cord runs freely and gathers evenly on a packed sample — a drawstring that closes cleanly when empty can bunch on one side when full.
