Hello friends! Happy New Year to you all. I need some assistance with purchasing yarn to make an Irish flag pattern scarf for a dear friend. He is fighting mouth cancer and has to keep his face covered. I offered to knit him a scarf and he asked for the Irish flag. Now I know that I need white, green and orange yarn ... but I do not Pintrest, etc., so I was wondering if I should purchase specific shades of green and orange. I want to make this as close to the real colors as possible since it is a gift. Any help or patterns that give specific colors would be great. Thanks in advance :)
