Several have asked for the pattern that I use to knit my squares with. I get bored easily with straight knitted squares and the pattern I originally used for the diagonal squares was rather more complicated so it needed concentration and watching telly too was out of the question so I have designed my own version...these I can almost knit in my sleep now [just hope you can understand my instructions]. Here is what I do to come up with a square that measures about 4 1/2" or about 11 1/2cm.
As requested here is a picture of one I made earlier so you can see what the squares look like when made up and edged. :-) Your wish is my command :-)
Using double knitting wool and 4mm needles throughout cast on 3 stitches.
1st row Yfwd, k3 4 stitches
2nd row Yfwd, k4 5 stitches
3rd row Yfwd, k5 6 stitches
4th row Yfwd, k6 7 stitches
5th row Yfwd, k7 8 stitches
Continue in this fashion until you have 35 stitches on your needle
33rd row K2tog k33 34stitches
34th row K2tog p31 k1 33 stitches
35th row K2tog k31 32 stitches
36th row K2tog k30 31 stitches
37th row K2tog yfwd, [yrn p2tog] 14 times. k1 30 stitches
38th row K2tog k28 29 stitches
Rows 33 to 38 form the pattern. Continue like this reducing stitches as you go til you get to
61st row K2tog yfwd, [yrn, p2tog] twice, k1. 6 stitches
62nd row K2tog, k4 5 stitches
63rd row K2tog, k3 4 stitches
64th row S1, k3tog psso.
I hope this all makes sense to you but if you need more instructions please just ask.
