The pattern is made with Loops and Threads "Impeccable". It is a worsted weight yarn, but any worsted weight yarn is fine for this outfit. This little pattern is great for beginners, it is all basic crochet skills, and straight forward. The decals on the outfit, I bought at my local dollar store to decorate the jacket. The pattern makes up for sizes 0-3 and 3-6 months. It is a perfect little present for a new mother, or great for selling at craft fairs and such.
Pattern instructions are for the hat, pants, jacket, belt and mitts. Soft worsted weight yarn was used. I used "Loops n Threads", but any worsted weight yarn is fine. The decals that I added were things I had myself. You can dress this uniform up or down as you wish. Easy to read and follow instructions. A great gift for a baby shower, or for that new parent that is also a marine. Makes great prop pictures for a new baby. Pattern can be made for 0-3 months or 3-6 months.
