Sweaters that have a knit collar are typically referred to as "mock neck" or "turtleneck" sweaters. These types of sweaters have a collar that is made from the same knit material as the rest of the sweater. The collar is designed to sit higher on the neck, providing extra warmth and a stylish look. Mock neck and turtleneck sweaters are popular choices for colder weather and can be found in a variety of styles and colors. **

While poodles do have curly and soft fur, it is not typically used for knitting sweaters. Poodle fur is not as commonly used for yarn as other types of wool, such as sheep's wool or alpaca wool. Additionally, poodle fur is not as readily available in large quantities as other types of wool. It is also important to consider ethical concerns when using animal fur for knitting projects. **

The sweaters that have a cable knit pattern are the cream-colored turtleneck sweater and the navy blue crewneck sweater. Both of these sweaters feature a classic cable knit design that adds texture and visual interest to the garments. The cable knit pattern is a timeless and cozy style that is perfect for the colder months. **

As an AI, I don't have personal preferences, but I can tell you that fine-knit turtleneck sweaters can look very stylish on men. They can give a sophisticated and polished look, especially when paired with tailored trousers or a blazer. However, whether or not someone likes this style ultimately comes down to personal taste. **

To knit socks with felting wool, you will need to use a larger needle size than you would for regular knitting. This is because felting wool tends to be thicker and bulkier, so a larger needle will help create a looser fabric. Additionally, you will want to knit the socks slightly larger than your desired size, as the felting process will shrink the fabric. Once the socks are knitted, you can felt them by washing them in hot water and agitating them to shrink and tighten the fibers. Keep in mind that felting wool can be more challenging to work with than regular yarn, so it's a good idea to practice with a small swatch before starting on the socks. **

It is generally a good idea to wash new knit cardigans before wearing them to prevent shedding. This can help remove any excess fibers that may be prone to shedding and also help to soften the fabric. However, it is important to check the care instructions on the garment to ensure that it can be safely washed. Some knit cardigans may require special care, such as hand washing or dry cleaning, so it is important to follow the manufacturer's recommendations. **

Knitting socks with needle size 100 would be extremely challenging, as this needle size is much larger than what is typically used for sock knitting. The resulting fabric would be very loose and open, and the socks would likely be too large and not fit properly. It would be best to use a much smaller needle size, such as US 1 (2.25mm) or US 2 (2.75mm), to achieve the tight gauge and small stitches needed for a well-fitting and durable pair of socks. **
