12 ½ Inch Inside Addition Block Tutorial

This post was originally written for the BeeInspired group – it’s the block I’ve requested the girls make for me this month. I thought I’d share it here as well.

The original block by Jessica (@alittlegressica) is designed at 8" unfinished. Upsizing it is fairly simple. Here’s what you will need

4 HST units with an unfinished size of 5 ½̎  using background and feature fabrics
(I’m not including cutting measurements or sewing techniques here. I know everyone has their own favourite HST method. I like to make mine oversized and trim. Links to resources are included at the bottom of the post);
4 x 3" squares background fabric
2 x 3" squares feature fabric

1 x  3" x 8" strip feature fabric

Sew 2 background squares to either end of the feature fabric strip and sew two feature fabric squares to one background fabric square each; sew the HST units to the 2 square units; then the two sewn sections to the centre strip and admire! (That’s black arrow, then green arrow, then red

As promised, here are some links:
