Red Heart bought out Chadwick’s but continued to sell their yarns under the Chadwick’s name.

This yarn was made for and sold exclusively by Woolworths in the UK. It is listed among the Woolworth knitting Yarns in the first Woolworth’s Knitting Magazine.

This and other Chadwick’s Courtelle yarns are also listed among Woolworth’s knitting yarns in Woolworth Knitting Magazine Issues 2 to 7.
