Great pattern here - relaxed style with easy lace, a really good way to introduce yourself to lace knitting. Styled here for cooler summer days, these designs would also be great in a wool or wool-blend for autumn/winter.
You get the jumper and the cardi instructions on the one pattern, they are shown in King Cole's Paradise Beaches yarn which is all man-made but looks and feels like soft cotton. You could, subject to the usual caveat of checking your tension, use just about any other DK yarn.
The second image shows you what you need. We stock the yarn in lots of colours, you'll find it in the "Yarn" section and knitting needles in the "Everything Else" section.
If you don't mind us folding your pattern in half you can choose small letter postage but if you want it unfolded you'll need to choose large letter or you can of course collect it from us.
