Slouchy hat crochet pattern – rhombus stitch
Step-by-step crochet instructions
Crochet the hat from the bottom to top.
Step 1
Make a foundation chain of 73 chains or multiples of 9 chains plus 1 additional chain. I count all the loops including the loop on my hook. (To adjust the pattern, the foundation chain should be multiples of 9 chs plus 1ch for an even number of repeats and mult. of 9 chs for an odd number of repeats. The foundation chain should have an odd number of chs.) Join it into a ring with the slip stitch.
Step 2
1st round – ch2, hdc to end plus sl.st.1 into 2nd ch
2nd round – ch3, dc1 into loop*, [dc1, dc1 into loop] to end + sl.st.1 into 3rd ch
*dc into loop – work dc into the loop right below your chain from the right side of the garment
3rd and 4th rounds = 2nd round
Step 3
Increase
5th round – ch3, dc1 into loop, then use two dcs before starting point and work dc1 into each loop, [inc1, (dc1, inc1) x 2, sk2, dc2 into loops, dc2 into loops above the 2 skipped dc] to last 5 chs; inc1, (dc1, inc1) x 2 + sl.st.1 into 3rd ch
After the increase, you should have 96 chains and one loop on your crochet hook.
Step 4
Work the pattern without increasing chs
6th round – sl.st.1 into the next ch, ch3, [(dc1 into ch, dc1 into loop) above one dc of the prev. round, dc1 into loop, sk1, dc5, dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round] to last repeat; dc1 into ch, dc1 into loop) above one dc of the prev. round, dc into loop, sk1, dc5, dc dec1, (dc1 into loop) x 2 + sl.st.1 into 3rd ch
7th round – ch3, [dc1, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc3, dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc1] to last repeat; at the end of the last repeat, do not work the very last dc1, just work sl.st.1 into 3rd ch
8th round – ch3, [dc2, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc1, dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc2] to last repeat; at the end of the last repeat, work just one dc instead of 2 + sl.st.1 into 3rd ch
9th round – ch3, [dc3, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc dec*1, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc3] to last repeat; at the of the last repeat, work two dc instead of 3 + sl.st.1 into 3rd ch
*dc dec – double crochet decrease – yo, insert a crochet hook into the following chain, and draw the yarn through (you should have 3 loops on your hook). Then pull the yarn through the first 2 loops on the hook (now you have 2 loops left on the hook). Do again yo, insert a hook into a loop right below the following chain, and draw the yarn through (you should have 4 loops on the hook). Pull the yarn through the 1st 2 loops on your hook and then through the remaining 3 loops on the hook.
10th round – ch3, [dc3, dc dec1, sk1, dc2 into loops, dc2 into loops of 2 skipped dc of the prev.round, dc4] to last repeat; dc3, dc dec1, sk1, dc2 into loops, dc2 into loops of 2 skipped dc of the prev.round, dc3 + sl.st.1 into 3rd ch
11th round – ch3, [dc2, dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc3] to last repeat; at the of the last repeat, work two dc instead of 3 + sl.st.1 into 3rd ch
Step 5
Decrease
12th round – ch3, [dc1, dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc dec1, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc2] to last repeat; at the of the last repeat, work one dc instead of 2 + sl.st.1 into 3rd ch
13th round – ch3, [dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc dec1, dc1, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc1] to last repeat; dc dec1, dc1 into loop, (dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc dec1, dc1, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop + sl.st.1 into 3rd ch
14th round – sl.st.1, ch2, dc1 into loop, [(dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc dec2, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop, sk1, dc dec*1] to last repeat; [(dc1 into loop, dc1 into ch) above 1 dc of the prev.round, dc dec2, (dc1 into ch, dc1 into loop) above 1 dc of the prev.round, dc1 into loop + sl.st.1 into 3rd ch
15th round – ch3, dc1 into loop, then use two dcs before starting point and work dc1 into each loop, [dc dec2, sk2, dc2 into loops, dc2 into loops of two skipped dc of the prev. round] to end + sl.st.1 into 3rd ch
16th round – ch3, dc3 into loops, [dc dec*1, dc3 into loops] to last 2 chs; yo, sk1, insert a hook into a following ch, grab the yarn, and pull it, resulting in 3 loops on your hook. Then draw the yarn through the first 2 loops on the hook. Insert your hook into the 3rd ch from the starting point, grab the yarn, and pull it through the chain and 2 loops on your hook.
17th round – ch3, dc dec into loops to end + sl.st.1 into 3rd ch
18th round – sc dec to end. Then cut the yarn and secure it from the wrong side of the hat.
