What are the sizes for changing the middle of blankets to accommodate your needs? This article has the square version plus four other sizes common for babies, kids, and multiple bed sizes. Those in hospitals or seated positions such as wheelchairs must keep their legs warm.
I have provided a crochet diagram. Written instructions for the square version, initially supplied by Yarnspirations, are also included. The four rectangle swatches used Caron One Pound.
Even with a striping colour like Red Heart Super Saver Stripes, this type of stitch is fun to watch and see what happens.
This article features the Small Crochet Interlocking Shells perfect for Baby Blankets. Below is the medium-size, and the colour is changed every four rounds instead.
Sizing
Each size has been checked to see how it will grow. For example, the XL has to have a long enough centre so that when it grows outward, it can reach the width and length of a twin bed.
The square can be made as big as you need. Written instructions for this size are available here.
This size Small (with yellow centre) is the base for baby blankets, child-size blankets, teenager blankets, throws, queen-size with drape, and king-size for both mattress tops and drapes.
Medium (with blue centre) is for wheelchairs, baby blankets, child-size and teenager blankets.
Large (with green centre) is for child-size and teenager-sized blankets.
X-Large (with orange) is for twin-size, cribs, cradles and queen-size with no drape.
Square Size Version
Match the hook to the ball band recommendation if you prefer a square size. A free tutorial was included. The original square version was completed with Caron Chunky Cakes yarn.
Small Sizing
This size is very versatile in sizing.

Instructions - Small Size
With A, ch 17 (multiples of 6 chs + 11).
1st rnd: Vst in the 5th ch from hook. Sk 4 chs, ch 1, 1 dc in next ch, vst in next ch, 1 dc in next ch. Sk 4 chs, ch 1, (Vst in last ch, ch 1) 3 times. Rotate the project to continue to work on the underside of the chain. Sk 4 chs, 1 dc in next ch, vst in the next, 1 dc in next ch. Sk 4 chs, ch 1, vst in next ch, ch 1, 1 dc in same st as the last vst. Ch 1, join with sl st to top of beg ch 3.
2nd rnd: Sl st to next ch-1 sp. Ch 1, 1 sc in same sp. (Shell into the ch-1 sp of next vst. 1 sc in next ch-1 sp.) 7 times. Shell into next ch-1 sp. Join with sl st to beg sc. Break A. 8 shells and 1 sc between each around.
3rd rnd: With B, join with sl st to same st as join. Ch 4 (counts as 1 dc and ch-1 sp), 1 dc in same st as join. Ch 3 - corner sp, vst into same st as join. Ch 5, (vst in next sc, ch 5) twice. Corner st in next sc. Ch 5. Corner st in next sc. Ch 5. (vst in next sc, ch 5) twice. Corner st in next sc. Ch 5. Join with sl st to 3rd ch of beg ch 4. 4 vsts on long sides and 2 vsts on the shorter sides.
4th rnd: Sl st to next ch-1 sp. Ch 3 (counts as dc), 6 dc in same ch-1 sp. 1 sc in ch-3 corner sp. Shell in next ch-1 sp. (Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp) three times. 1 sc in ch-3 corner sp. Shell into next ch-1 sp, Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp. 1 sc in ch-3 corner sp. Shell in next ch-1 sp. (Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp) three times. 1 sc in ch-3 corner sp. Shell into next ch-1 sp. Sc over the ch-5 of prev rnd in the 4th dc of the shell below. Join with sl st to top of beg ch 3. Break B. 4 shells on long side, 2 shells on short side.
TIPS:
- The yarn must be stopped entirely and restarted again in the single in corner space to look consistent.
- Mark corner stitches with a stitch marker to make it easier to follow.
- In 5th round, we are skipping the shells and working with single crochet stitches only.
- The 5th and 6th rounds repeat the 3rd and 4th rounds. The rounds are getting bigger between corners. The 5th and 6th rounds do not show how many shells or vsts there are between corners, as the pattern will become obvious. Each time you repeat, you will have increased by 1 vest or shell per side.
5th rnd: With B, attach with sl st same st as join. Ch 4 (counts as 1 dc and ch-1 sp), 1 dc in same st as join. Ch 3 - corner sp, vst into same st as join. Ch 5, (vst in next sc, ch 5) Rep ( ) to corner st. Corner st in next corner sc. Ch 5. (Vst in next sc, ch 5). Rep ( ) to corner st. Corner st in next corner sc. Ch 5, (vst in next sc, ch 5). Rep ( ) to corner st. Corner st in next corner sc. Ch 5, (vst in next sc, ch 5) Rep ( ) to corner to beg ch 4. Join with sl st to 3rd ch of beg ch 4. 5 vsts on long sides and 3 vsts on the shorter sides.
6th rnd: Sl st to next ch-1 sp. Ch 3 (counts as dc), 6 dc in same ch-1 sp. 1 sc in ch-3 corner sp. Shell in next ch-1 sp. (Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp). Rep ( ) to corner sp. 1 sc in ch-3 corner sp. Shell into next ch-1 sp, (Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp). Rep ( ) to corner sp. 1 sc in ch-3 corner sp. Shell in next ch-1 sp. (Sc over the ch-5 of prev rnd in the 4th dc of the shell below, shell into next ch-1 sp). Rep ( ) to corner sp. 1 sc in ch-3 corner sp. Shell into next ch-1 sp. Sc over the ch-5 of prev rnd in the 4th dc of the shell below. Join with sl st to top of beg ch 3. Break B. 5 shells on long sides, 3 shells on short sides.
Rep 5th and 6th rounds until the desired size. Each colour is used for just two rounds before switching to the next.
The crochet diagram shows the small size. The red chain and double crochet are the repeating segments when the chain is longer for medium, large, and extra large.

Crochet Diagram
This is the basic structure of the interlocking shell blankets. In red, you will see a repeating sequence. You can download this diagram for your reference. This is a small size, for example. The medium, large, and x-large versions, the chain and starting round 1 have a more extended centre, as shown in the tutorials below.

How do we get the written pattern to test the baby blanket?
Wendy Maruna says
We have taken the written pattern down at this time. We will need to revisit it later in the year when time is plentiful to devote to correcting the issues. Thank you
Sandi Grandberry PhD says
I know you have plenty of notes, but I just finished the large and extra large. Only one more comment. I hope you got my others ?. Shell set up 2nd round: Sl st to next ch 1 sp. Ch 1 , 1 sc in same sp. Shell into next ch 1 sp. (1sc into next ch 1 sp) 9, 11, 19 …
Those numbers need to be added for each size.
Mikey says
I did get your others. I have taken down the pattern. 3 testers have 3 different recommendations on the same instructions which conflict with each other. So I need to revisit this pattern another time and retest again. I lost my train of thought and was super confused. It's best I recrochet again and figure out which tester is right. I don't know at this moment.
Liz Ring says
Hi there! I have now tested the Medium to row 6. I have done it with only the pattern since I'm just learning to follow a chart(thanks Mikey!) Found several errors which will follow into the large and extra large sizes I'm sure. round one: You forgot the opening bracket for the repeats, and repeat count is in error, or, there is a missing instruction. I would say it should read: Vst in 5th ch from hook, ch 1, sk next 4 chs, (1 dc in next ch, vst in next ch, 1 dc in next ch, ch 1,) sk next 3 ch, rep ( ) 1, 2, 6 times. Sk next 4 chs..........and then the next repeat numbers should be 1,2,6 again.
2nd round should be 9 times instead of 7 times.
4th round the first rep ( ) should read once instead of twice.
5th round *Ch 5, sk next 7 dc, vst in next sc, ch 5) 4, 5, ? times. (sorry, didn't check the math for the extra large size.
Mikey says
Excellent. The way you typed out the corrections was really helpful. Appreciate that. I have updated.
Gwen Burnham says
Mikey, I am working on the medium size, having problems but see now you have updated pattern. Can't find the pattern. Is there a link?

Mikey says
I have taken down the pattern. Three testers disagreed with each other in the results. So I need to recrochet this again and see which tester is right on. I got so confused, I took down the pattern.
