Test 1, feel: rub it between finger and thumb. Circle one in each pair.
Test 2, stretch: pull gently across, then let go. Did it come back?
Test 3, water drop: one drop, count to ten. Soaked in, beaded up, or spread out?
| Swatch | Feel: smooth or rough | Feel: warm or cool | Feel: thick or thin | Stretch: came back / stayed stretched / no stretch | Water: soaked in / beaded / spread | My guess at the fiber | Good for making |

| A | smooth / rough | warm / cool | thick / thin | ||||
| B | smooth / rough | warm / cool | thick / thin | ||||
| C | smooth / rough | warm / cool | thick / thin | ||||

| Swatch | A | B | C | D | E | F |
|---|---|---|---|---|---|---|
| Wrinkle 1 to 3 |

4a. Write the real fiber next to each letter, then check your guess.
| Swatch | Real fiber | Was my guess right? |
|---|---|---|
| A | yes / no | |
| B | yes / no | |
| C | yes / no | |
| D | yes / no | |
| E | yes / no | |
| F | yes / no |
4b. For each use, write the swatch letter you would pick. Then give two pieces of evidence from your own tests.
| The use | My swatch | Evidence 1 (from my tests) | Evidence 2 (from my tests) |
