I can't get textures to work

hey guys.  I was making a minecraft mod.  everything was going good until I couldn't get textures to work.

I'm using forge 1.7.10 and my textures are saved to, "assets.WarriorMod.textures.items," I don't know what I did wrong.

here is my Item class...

package com.Joeyalbo.item;

import com.Joeyalbo.lib.refstrings;

import cpw.mods.fml.common.registry.GameRegistry;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

public class WarriorStick {

public static void mainRegistry(){

initializeItem();

registerItem();

}

public static Item WStick;

    public static void initializeItem(){

    WStick = new Item().setUnlocalizedName("WStick").setMaxStackSize(64).setCreativeTab(CreativeTabs.tabMaterials).setTextureName(refstrings.MODID + ":WStick");

    }

    public static void registerItem(){

    GameRegistry.registerItem(WStick, WStick.getUnlocalizedName());

    }

}
