Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 22 fabric packs to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the craft room and check the inventory.

Count the 88 fabric packs before visitors arrive. Confirm a clear entrance and an accessible work area at the craft room, then give each of the 4 group leads the same timing sheet.

Supplies: 88 × $9.95 = $875.60. Reserve: $875.60 × 0.10 = $87.56. Planned total: $963.16. This is a planning calculation using the supplied prices.

Remove 22 units, leaving 66. Supplies become $656.70; a 10% reserve adds $65.67, for a total of $722.37.

Join Community Sewing Circle this Tuesday at the craft room. Meet neighbors, learn together, and take part at your own pace. We will share the available fabric packs across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Community Sewing Circle Tuesday · craft room Welcome! Ask the desk about available fabric packs and today’s small-group activities.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: fabric packs,88 ```

The row `fabric packs,88` should pass. The row `fabric packs,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Community Sewing Circle Location: craft room; day: Tuesday. Inventory: 88 fabric packs, allocated as 4 groups × 22. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 22 fabric packs per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare fabric packs. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of fabric packs before checking the group capacity. Keep the reply specific to the craft room session and offer a clear next step: speak with the welcome desk.
