This is a crocheted piece.
I made a simple coaster using crochet back and forth stitches.
This is a knitted pattern based on knit stitches.
I've made a few small changes so that I don't have to knit the edges.
Although it is a very basic item, I realized that there were no free coaster recipes until now, so I decided to make one. Crocheted coasters are very useful in our home.
It was a good opportunity to add some knitting.
When I need to grab a pot with a hot handle, I don't need to get out a larger potholder because I have small hands, and two coasters like these will do the trick.
Even if you knit both one for heavy use in the kitchen and one for guests, they are small enough that you can store them in a corner.
I think mass production would be fun if you changed the thread.
Even if you combine two colors of yarn, it's exciting to see what color knitted fabric you'll get.
This was knitted using extra thick yarn.
Although the knitted fabric has few gaps, if you are going to grab something hot, try using thicker yarn as the thin yarn may transmit the heat.

Instructions
Please refer to the crochet pattern along with these instructions.
①Cast on 15 chain stitches.
This uses extra thick yarn, so if you want to increase the number of stitches when knitting with thinner yarn, try increasing the number of stitches by +4.
To be precise, it's OK as long as the number of cast-on stitches is a multiple of 4 + 3.
The 15 stitches I knitted are 4 x 3 + 3, so if I were to add one more pattern, I would make it 4 x 4 + 3 and cast on 19 stitches.
Only the first row is knitted in an alligator stitch, and the symbol written upside down at the bottom of the knitting pattern indicates the first half of the first row that you knit after casting on.
In the first half of this first row, scoop up one strand on the other side of the cast-on chain and the back of the knot and make a circular stitch.

At this symbol, knit three quarter stitches into the first stitch of the previous row (or cast-on).
②For the second half of the first row, pick up the remaining chain of the cast-on stitch that you did not pick up in the first half and knit it.
③From the second row onwards, do not knit in a crisscross pattern, but knit back and forth without increasing or decreasing the number of stitches.
Once you have knitted up to the 13th row, cut the yarn and process it.
④ When you finish knitting, the edges of the knitted fabric will be curled as shown in the image below, but if you use a steam iron while holding it above the fabric, the knitted fabric will settle down.
