The cake is a lie. But the toilet paper cover isn't.
Dimensions: To fit your roll of toilet paper. The sample measures 4.75" in diameter by 4.75" high (12cm by 12cm)
Supplies:Needles: To give you a fabric you like with the yarn you're using. The cover is worked entirely in the round, so you're looking for DPNs or circs or both. Sample was made with US8/5mm needles.
Yarn needle: To weave in ends
Buttons (optional): One for each cherry. (Sample used 5 1/2" two-hole buttons.) They aren't strictly necessary, but I found it easier to attach the cherries and frosting by anchoring them on a button.
Stitch markers: scraps of yarn in a contrasting color work nicely. You'll want one to mark the start of the rounds and 8 more (different style) to mark the pattern repeats
Toilet paper roll: Yep. This is another example of couture toilet roll fashion. Custom made to fit that particular roll.
Yarn: Brown, white, and red.
If your roll of toilet paper is larger, you may need more yarn.
This is worked from the bottom up. While gauge is less important than getting a fabric that you like, you need to know your gauge so you know how many stitches to cast on. (For this sample, I cast on 54 st, at a gauge of 4sts/in. This fit nicely over a relatively small roll of toilet paper.)
Chocolate cake toilet paper roll cover:
Please note: you are making this inside out. You'll be knitting all the way through, but the reverse stockinette side is the right side. (This also explains why the pattern calls for ssk instead of k2tog: ssk looks better on the wrong side.) Please turn it inside out before weaving in ends. Also, you'll be making this a little long, but because of the magic of stockinette, this will give the bottom edge a chance to curl fairly neatly under the roll.
Sides and top:
With brown, cast on enough stitches (on a circular needle or onto dpns) to go around the roll of toilet paper. Join without twisting, and knit until piece is about an inch longer than the sides of the roll.
Frosting (make 5)With white, cast on 18 stitches, and join without twisting.
Round 1: k around
Round 2: k2tog around
Break yarn. Draw end through 9 stitches on needle, and pull nearly shut. Weave in ends.
Cherries (make 5)With red, cast on 9 stitches, and join without twisting. Knit three rounds.
Break yarn, leaving a fairly long tail. Draw end through 9 stitches on needle, and pull tight. Weave cast-on tail through the cast-on row and pull tight, catching the other tail within the sphere. (That's the stuffing.) Optional: catch tail under one stitch on opposite side of purse string closure, so the tail forms a loop and the cherry looks something like this from a side view:
Block pieces as desired. Sew cherries and frosting to cover. If you've made the optional tail-and-loop for the cherries, you can pull those through the frosting circles, then pull them through the cake, then pull them through the holes of buttons (loop through one hole, single strand through the other), and tie them in a square knot. If you prefer another way of anchoring bobbles, please use that method.
So there you have it. A toilet paper cover that looks sweet. Even if it is a lie.
