This is the kind of Christmas project that gets made once and used for twenty years. It is a proper sewing project rather than an afternoon craft - there is hemming, pressing, quilting through three layers and a bound edge - but none of the individual steps is difficult.
It starts from a printed fabric panel, which does the design work for you. The panel arrives as one large piece with the pockets, numbers and backing all marked out, and your job is to cut, press, sew and assemble.
Two pocket styles
The gusseted version has deep pockets with a fold at each side, so they hold more than a chocolate - small toys fit. The flat patch version is simpler and quicker, with each pocket cut and sewn individually. The quilting and binding stages are identical either way.
The part that needs a walking foot
Once the panel, wadding and calico backing are layered, you are sewing through three thicknesses. A walking foot has feed dogs on the top as well as underneath, so all three layers move through together instead of the top one shifting. Without it the layers creep and the finished piece puckers.
Numbers in random order
Most printed panels scatter the numbers rather than running 1 to 24 in sequence. That is deliberate - hunting for the right pocket is half the fun for children, and it is the detail that makes these worth keeping.
