Items not destroying.

Hello, I just almost got everything in a crafting system complete :). I just have one more bug, when I craft something the items used do not delete! How do I fix this, what am I doing wrong!

Code:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System.Linq;
 
 public class PlayerInventory : MonoBehaviour {
 
     public List<Item> MyItems = new List<Item>();
 
     public Weapon weapon1;
     public Weapon weapon2;
 
     public Clothes MyClothes;
 
     public PlayerWeaponManager pwm;
     public PlayerClothesManager pcm;
 
     public void AddWeapon(Weapon we){
         if(networkView.isMine){
             if(we.weslot == 1){
                 weapon1 = we;
             }
             if(we.weslot == 2){
                 weapon2 = we;
             }
             pwm.SwitchWeapon(we.weslot);
         }
 
     }
 
     void OnGUI(){
         if(GUILayout.Button("Add wood")){
             MyItems.Add(Item.Wood());
         }
         if(GUILayout.Button("Craft wood-wall")){
             Craft(Craftable.WoodenWall());
         }
     }
 
     public void AddClothes(Clothes _clothes){
         MyClothes = _clothes;
     }
 
 
 
     public void AddItem(Item added){
         if(networkView.isMine){
             MyItems.Add (added);
         }
     }

     public void Craft(Craftable recipe){
         bool b = CheckItems (recipe.InputItems);
         if (b) {
             foreach(Item it in recipe.InputItems){
                 MyItems.Remove(it);

             MyItems.Add(recipe.output);
         }
         else{

         }
     }

         return !check.Except(MyItems).Any();
     }*/
     public bool CheckItems(List<Item> check) {
         foreach(Item inventoryItem in MyItems) {
             if (check.Contains(inventoryItem)) {

                 if(check.Count == 0) {
