Yarning over before purling is a common knitting technique used to create an intentional hole in your fabric, often seen in lace patterns. To perform a yarn over (YO) before a purl stitch, you first bring the yarn to the front of your work as if you were going to purl. However, instead of going directly into a purl stitch, wrap the yarn over the top of the right needle and bring it back to the front again. This creates the yarn over. Then, insert the right needle into the next stitch purl-wise and complete your purl stitch as usual. The YO before a purl can feel a bit awkward at first compared to a YO before a knit stitch because of the yarn positioning, but with practice, it becomes more natural. Remember, the yarn over does not count as a stitch on the needle but will create an extra stitch as you work it on the following row, so plan your project accordingly.
The United States Federal Reserve and Bureau of Engraving and Printing incorporate various security features into U.S. currency to prevent counterfeiting. One such feature is the use of magnetic ink, which contains iron oxide and can be detected by special machines. However, this technology was not introduced until the 1996 series redesign when new $100 bills were issued. Prior to this, neither $1 nor $5 bills contained magnetic ink. For the $1 and $5 denominations, magnetic ink wasn't included until the latest series updates. Current $5 bills (Series 2006 onwards) do contain magnetic ink, but $1 bills do not. This is because the $1 bill remains in circulation for a long time and has not been redesigned with advanced anti-counterfeiting measures due to its low denomination and high usage.
The safety of using baby oil on PVC (Polyvinyl chloride) depends largely on the specific formulation of the baby oil and the type of PVC material. Generally, baby oil consists primarily of mineral oil, which is a petroleum-based product. Pure mineral oil typically does not pose significant risks to most types of PVC. However, some baby oils may contain additional fragrances or other additives that could potentially react with or degrade certain PVC products, particularly those that are softer or more flexible due to higher levels of plasticizers. It's important to note that over time, any oil can cause some degradation, softening, or discoloration of PVC, especially if the PVC item is exposed to sunlight or heat. If you're considering using baby oil on PVC, it's advisable to test a small, inconspicuous area first to ensure there's no adverse reaction. For best results and to avoid potential damage, consider using products specifically formulated for cleaning or conditioning PVC.
