Raspberry Rucksack Sew Along Number Two - Cutting Pattern Pieces and Fabric

All the pattern pieces of the Raspberry Rucksack are simple rectangles! Here’s what you need to make the pattern pieces.

Firstly, it’s nice to have sturdy paper so the pattern pieces are durable and can be used multiple times. I like to use this brown packaging paper you can find at Joann’s or Walmart or other basic stores. Another good option is freezer paper or any paper that is large enough for the pattern pieces.

Secondly, use a ruler that has a true 90 degree angle. You don’t need to have one of these fiberglass quilter’s rulers, you can use a simple straight edge ruler combined with a piece of typing paper or a book. It’s just helpful to have something that you can use to check if your angles are exactly 90 degrees.

Thirdly, you’ll need a pen and paper cutting scissors.

Starting on a straight edge of whatever paper you are using, make a line perfectly perpendicular to the paper’s straight edge. Once you have one straight line horizontally (the papers edge) and vertically (the line you just drew), you can base all of your measurements off of these two lines.

Using the measurements provided in the pattern and these two lines, cut out all the pattern pieces.

Once all the paper pattern pieces are cut, you can trace them out on your fabric. Trace around one pattern piece and then lay another piece right next to it so they can share the same line. Less marking, less cutting, less fabric!

You can also be strategic about cutting out the fabric pieces. You can lay the lining and outer layer on top of each other and cut both pieces at the same time. Just be sure to check that both pieces have their grainlines going the same direction. You can get away with cutting two layers stacked on top of each other like this, especially if the lining is a thin material like quilting cotton. I wouldn’t recommend also trying to stack interfacing on however. Cut the interfacing separately.

Once all your pattern pieces are cut you can move on to sewing!

Outer Layer

The outer layer should be a heavyweight fabric such as cotton canvas, waxed cotton canvas, heavyweight denim or corduroy, or upholstery fabric.

This bright yellow is 10 oz duck canvas from Joann’s Fabric and Craft.

Lining

Using simple quilting cotton works well for the lining. You can use any woven fabric as long as it’s fairly lightweight and brings you joy! It’s nice to use a bright fabric on the inside of bags so it’s easier to find things and it’s like sunshine whenever you peak inside.

Interfacing

It’s easy to get overwhelmed in the interfacing department. Don’t over think it. Just choose something medium to thick in stiffness. You want something that has a stiffness similar to thick, nice paper (like card stock) but not something that feels like cardboard. This pattern requires sewing through many layers at one time, so you don’t want to overwhelm your machine with too thick of interfacing.

If you’re using waxed canvas or another stiff outer layer, interfacing may not be needed.

Webbing

It’s nice to use thick webbing for this pattern because it gives the bag a really durable and sturdy feel. Pick your favorite color of 1” (2.5 cm) webbing and make sure it’s the same size as the hardware you’re getting! I like to use cotton webbing because of the nice feel, but you can use nylon or other webbing.

Hardware

Two rectangle D rings and two (non-adjustable) slide adjusters. You can find these in a bunch of styles and colors and materials. Have fun picking something that matches your fabric and is the right size for your webbing.

Zippers

Last and not least, zippers! You need two zippers - a single pull zip for the front popup pocket, and a double pull bag zip for the main compartment. You can use any style of zipper you would like - metal, molded plastic, or coil. This pattern was drafted for a zipper that is 1 1/4” wide (a common zipper width - if you’re ordering online, #5 is the gauge you want to go with.)

Here are some things to know about zippers:

The length of the zipper is defined by the length of the zipper teeth, not the length of the total zipper including the tails on the ends. So if you’re using a cut-to-length zipper, you will want to add an additional 1/2” or 3/4” to each end for some extra breathing room on the double pull bag zip. For the pocket zip, it needs to be exactly 7” (Little) or 9” (Big) and the tails actually get cut off anyway, so you don’t have to worry about adding extra.

It can be somewhat difficult to locate double pull bag zips. Surprisingly difficult actually. Jacket zips are much more common. The good news is that many jacket zips can be turned into bag zips. Let me show you how.

Here is a visual of the difference between bag zips and jacket zips. Bag zips are open in the middle and are closed on the sides (just think of how a duffle bag zips!). A jacket zip is open on the sides and is closed in the middle.

Not all zippers can be changed like this - but molded plastic can! If you have a jacket zip you want to change to a bag zip, simply zip one of the zipper pulls right off the end (you may have to cut the end of the zipper). Then turn the zipper around so you’re holding the open teeth on the other end. Turn the zipper pull around so the wide end is facing the open teeth. Insert each side of the teeth into the wide end of the zipper pull and then slide it on. Be sure to check if the teeth are lined up properly. Sometimes one end gets longer or shorter than the other. Simply take the zipper pull off and reinstall if the teeth aren’t even on the first try.

One more note about zippers. You see how the red zip on the left is 1 1/2” wide and the orange zip on the right is 1 1/4” wide? That has to do with their gauge. See how much larger the teeth are on the red zipper? Online you often see zippers advertised by a number. Something like “Lime green coil zipper #7.”

The red zipper on the left is #10 molded plastic and the orange zipper is #5 molded plastic. For this pattern, #5 is what you want.

Most longish zippers you find in the stores are #5, so I don’t worry too much if you’re shopping local. But if you’re ordering online the numbers can be confusing so bare that #5 in mind.

If you like this orange molded plastic zipper in all these photos, I am going to be offering it for sale when I release the Raspberry Rucksack Pattern!

Here’s another online zip resource with a wide variety of good options and an easy ordering process: Zipper Source.

Bias tape

Bias tape is used to bind the raw edges of the very last seam in the Raspberry Rucksack. You can either make your own out of your lining material, or you can buy double fold 1/2” (12.7 mm) bias tape in a matching or contrasting color! The seam it’s going on has a seam allowance of 3/8” (1 cm. If you’re making your own, the strip should be 1 1/2” (3.8 cm) wide.

That’s it!

You’re well on your way to having your own Raspberry Rucksack! More posts in the sew along series will be trickling on in the next few days as I get ready to launch. Release date is March 6th!

Using Two Threads as an Alternative to Top Stitch Thread

The fantastic Sophie of Ada Spragg posted in her Instagram stories last year about using two threads as an alternative to top stitching thread. I’ve employed the trick on a few pairs of pants since and have been delighted with the results.

Simply thread the machine as normal and put both threads through the needle. If you don’t have two spools of the same color thread, you can wind two bobbins and use one of them in place of the second spool.

Play around with the tension and stitch length on some scrap fabric until the stitches are just right.

4 Free Underwear Patterns

Into having an abundance of comfortable, cotton undies? Yeah, me too. I scoured the internet to find the best free undies patterns and narrowed it down to these four. This year I want to get more comfortable sewing knits (if you haven’t noticed I tend to gravitate toward thick, woven fabrics around here haha). Undies seem like a good place to start, so if you’re also wanting experiment with sewing knits more, we can work on these undie patterns together!
