It seems that a larger wound needs more rags to be healed or bandaged. This needs further testing, but the current thinking is as follows:
{| border=1
!Wound Type
!Cotton weight
|----
|[[Wound:very light|Very Light]]
|0.1
|----
|[[Wound:light|Light]]
|0.2
|----
|[[Wound:medium|Medium]]
|0.3
|----
|[[Wound:bad|Bad]]
|0.4
|----
|[[Wound:severe|Severe]]
|0.5
|}
Or
<br>
{| border=1
!Wound damage
!Cotton weight
|----
|0-3033.3
|0.1
|----
|3133.4-6066.6
|0.2

|6166.7-9099.9
