Janome Purple Tip Sewing Machine Needles

I belong to a Janome sewing digest and have seen the ladies on the board (could be men as well, hard to see through the monitor screen) asking where they can find Janome Purple Tip Sewing Machine Needles . While I haven't used them as yet, I do know where you can find them as well as the Red Tip and Blue Tip Needles. the folks on the digest that have used the purple tipped needles swear by them to help prevent skipped stitches.

Here is some more information about the Purple Tip Needles from Amazon:

Janome Purple Tip Sewing Machine Needles are designed to prevent skipped stitches when sewing on stretch fabrics.

The Janome Purple Tip Sewing Machine Needles are great for sewing quilt layers and also for sewing across the hem.

The Janome Purple Tip Sewing Machine Needles are in size 90/14 and are 5 needles per pack.

Here is some more information about the Blue Tip Needles from Amazon:

• The Blue Tip needle is specially designed for Janome machines. The unique design has a slightly longer than normal scarf to cure skipped stitches and puckering in any problem fabrics especially synthetics. Size 75/11 Highly recommended for all Janome embroidery machines.

Here is some more information about the Red Tip Needles from Amazon:

• Janome Size 14 Red Tip Sewing and Embroidery Needles are designed for denser embroidery. Created in the same style as the classic Blue Tip needle, the Janome Size 14 Red Tip Sewing and Embroidery Needles provide the extra strength and durability needed for denser embroidery and thicker fabrics. This Janome Size 14 Red Tip Sewing and Embroidery Needles are equipped with a larger eye, which helps to prevent the thread breakage that can occur when working with tricky threads, such as metallic.

I would love to hear from those who have used these needles. Are they worth it? Did you have any trouble with them? Do your skipped stitches disappear when using them? Any comments that can help out your fellow sewers would be appreciated.
