Need to hold some stitches, or try on a garment mid-progress?
What about provisional cast ons?
Maybe you need the needles for another project? (Multiple WIPs are 100% endorsed here!) 
 
Stitch Noodles FANTASTIC!!
 
They are flexible hollow cords, you can quickly slip the end onto the tip of a needle and slide your stitches onto the cord. Then, easily do the reverse to get your stitches back on the needle!
 
There are two sizes:
MEGA are great for needles 4mm and up
NANO are perfect for smaller sizes down to 1.5mm
 
The sets are packaged in a cute pink tin and include the following lengths:
1x 150cm (colour)
2 x 60cm (white)
2x 40cm (MEGA black or NANO grey)
